Math Multiplication Quotes

That is the inescapable math of tragedy and the multiplication of grief. Too many good people die a little when they lose someone they love. One death begets two or twenty or one hundred. It's the same all over the world.

I still remember the day I got my first calculator Teacher: All right, children, welcome to fourth grade math. Everyone take a calculator out of the bin. Me: What are these? Teacher: From now on we'll be using calculators. Me: What do these things do? Teacher: Simple operations, like multiplication and division. Me: You mean this device just...does them? By itself? Teacher: Yes. You enter in the problem and press equal. Me: You...you knew about this machine all along, didn't you? This whole time, while we were going through this...this charade with the pencils and the line paper and the stupid multiplication tables!...I'm sorry for shouting...It's just...I'm a little blown away. Teacher: Okay, everyone, today we're going to go over some word problems. Me: What the hell else do you have back there? A magical pen that writes book reports by itself? Some kind of automatic social studies worksheet that...that fills itself out? What the hell is going on? Teacher: If a farmer farms five acres of land a day-- Me: So that's it, then. The past three years have been a total farce. All this time I've been thinking, "Well, this is pretty hard and frustrating but I guess these are useful skills to have." Meanwhile, there was a whole bin of these things in your desk. We could have jumped straight to graphing. Unless, of course, there's some kind of graphing calculator! Teacher: There is. You get one in ninth grade. Me: Is this...Am I on TV? Is this a prank show? Teacher: No.

He calculated the number of bricks in the wall, first in twos and then in tens and finally in sixteens. The numbers formed up and marched past his brain in terrified obedience. Division and multiplication were discovered. Algebra was invented and provided an interesting diversion for a minute or two. And then he felt the fog of numbers drift away, and looked up and saw the sparkling, distant mountains of calculus.

Before the work of Georg Cantor in the nineteenth century, the study of the infinite was as much theology as science; now, we understand Cantor’s theory of multiple infinities, each one infinitely larger than the last, well enough to teach it to first-year math majors. (To be fair, it does kind of blow their minds.)

That's the inescapable math of tragedy and the multiplication of grief

Obligasyon ko bang pasanin ang mga problema ng math? Bakit? Bababa ba ng bill ko sa internet pag nag-factor ako ng quadratic trinomial? Malulutas ba ng Laws of Exponents ang problema natin sa basura? Mababawasan ba ng Associative Law for Multiplication ang mga krimen sa bansa? Makakabuti ba sa mag-asawa kung malalaman nila ang sum and difference of two cubes? Maganda ba sa sirkulasyon ng dugo ang parallelogram, polynomial at cotangent? Makatwiran bang pakisamahan ang mga irrational numbers? Anak ng scientific calculator!

No matter how limited their powers of reason might have been. still they must have understood that living like that was just murder, a capital crime - except it was slow, day-by-day murder. The government (or humanity) could not permit capital punishment for one man, but they permitted the murder of millions a little at a time. To kill one man - that is, to subtract 50 years from the sum of all human lives - that was a crime; but to subtract from the sum of all human lives 50,000,000 years - that was not a crime! No, really, isn't it funny? This problem in moral math could be solved in half a minute by any ten-year-old Number today, but they couldn't solve it. All their Kant's together couldn't solve it (because it never occurred to one of their Kant's to construct a system of scientific ethics - that is, one based on subtraction, addition, division, and multiplication).

I can't multiply myself out of a paper bag. But when it comes to roots, I'm your man.

In the life of mathematics two plus two makes four; but in the mathematics of life two and two can make five or even three sometimes

Q and Beanpole and I giggled at the way our math teacher, Mr. Sung-Li, wore four pencils in his shirt pocket in case he was suddenly attacked by a multiplication problem or something.

As a result of this “racism smog,” many of our children have internalized all of the negative stereotypes inherent in our society’s views of black people. A student teacher at Southern University told me that she didn’t know what to say when an African American eighth-grade boy came up to her and said, “They made us the slaves because we were dumb, right, Ms. Summers?” Working with a middle schooler on her math, a tutor was admonished, “Why you trying to teach me to multiply, Ms. L.? Black people don’t multiply; black people just add and subtract. White people multiply.

There are two moments in the course of education where a lot of kids fall off the math train. The first comes in the elementary grades, when fractions are introduced. Until that moment, a number is a natural number, one of the figures 0, 1, 2, 3 . . . It is the answer to a question of the form “how many.”* To go from this notion, so primitive that many animals are said to understand it, to the radically broader idea that a number can mean “what portion of,” is a drastic philosophical shift. (“God made the natural numbers,” the nineteenth-century algebraist Leopold Kronecker famously said, “and all the rest is the work of man.”) The second dangerous twist in the track is algebra. Why is it so hard? Because, until algebra shows up, you’re doing numerical computations in a straightforwardly algorithmic way. You dump some numbers into the addition box, or the multiplication box, or even, in traditionally minded schools, the long-division box, you turn the crank, and you report what comes out the other side. Algebra is different. It’s computation backward. When you’re asked to solve

five suggestions that can work to open mathematics tasks and increase their potential for learning: Open up the task so that there are multiple methods, pathways, and representations. Include inquiry opportunities. Ask the problem before teaching the method. Add a visual component and ask students how they see the mathematics. Extend the task to make it lower floor and higher ceiling. Ask students to convince and reason; be skeptical.

One particular aspect of Siddhartha’s revelation of the outside world has always struck me. Quite possibly he lived his first thirty years without any knowledge of number. How must he have felt, then, to see crowds of people mingling in the streets? Before that day he would not have believed that so many people existed in all the world. And what wonder it must have been to discover flocks of birds, and piles of stones, leaves on trees and blades of grass! To suddenly realise that, his whole life long, he had been kept at arm’s length from multiplicity.

Humans came from something. We came from perfection in the form of math. We came from multiple homes and star systems. We came from indestructible energy known as Divine Love. It is the greatest frequency of all. And if you can feel it, you will never want to feel anything other than Divine Love.

5.4 The question of accumulation. If life is a wager, what form does it take? At the racetrack, an accumulator is a bet which rolls on profits from the success of one of the horse to engross the stake on the next one. 5.5 So a) To what extent might human relationships be expressed in a mathematical or logical formula? And b) If so, what signs might be placed between the integers?Plus and minus, self-evidently; sometimes multiplication, and yes, division. But these sings are limited. Thus an entirely failed relationship might be expressed in terms of both loss/minus and division/ reduction, showing a total of zero; whereas an entirely successful one can be represented by both addition and multiplication. But what of most relationships? Do they not require to be expressed in notations which are logically improbable and mathematically insoluble? 5.6 Thus how might you express an accumulation containing the integers b, b, a (to the first), a (to the second), s, v? B = s - v (*/+) a (to the first) Or a (to the second) + v + a (to the first) x s = b 5.7 Or is that the wrong way to put the question and express the accumulation? Is the application of logic to the human condition in and of itself self-defeating? What becomes of a chain of argument when the links are made of different metals, each with a separate frangibility? 5.8 Or is "link" a false metaphor? 5.9 But allowing that is not, if a link breaks, wherein lies the responsibility for such breaking? On the links immediately on the other side, or on the whole chain? But what do you mean by "the whole chain"? How far do the limits of responsibility extend? 6.0 Or we might try to draw the responsibility more narrowly and apportion it more exactly. And not use equations and integers but instead express matters in the traditional narrative terminology. So, for instance, if...." - Adrian Finn

It wasn’t my fault that until that day I had never heard the word “multiplication.” It wasn’t something I’d learned in school, and my family didn’t sit around and work on math problems. But to a little kid who wanted to do well in school, it was a crushing defeat. In my immature brain, I didn’t understand the difference between intelligence and knowledge. So I assumed I was an idiot. I may not have known multiplication that day, but when I came home and told Papaw about my heartbreak, he turned it into triumph. I learned multiplication and division before dinner. And for two years after that, my grandfather and I would practice increasingly complex math once a week, with an ice cream reward for solid performance. I would beat myself up when I didn’t understand a concept, and storm off, defeated. But after I’d pout for a few minutes, Papaw was always ready to go again. Mom was never much of a math person, but she took me to the public library before I could read, got me a library card, showed me how to use it, and always made sure I had access to kids’ books at home.

[Lemaire] has been working on the thirteenth-root challenge for a number of years. Previously, his best time had been a sluggish 77 seconds. Afterward, he told the press, "The first digit is very easy, the last digit is very easy, but the inside numbers are extremely difficult. I use an artificial intelligence system on my own brain instead of on a computer. I believe most people can do it,but I also have a high-speed mind. My brain works sometimes very, very fast.... I use a process to improve my skills to behave like a computer. It's like running a program in my head to control my brain." "Sometimes," he said, "when I do multiplication my brain works so fast that I need to take medication. I think somebody without a very fast brain can also do this kind of multiplication but this may be easier for me because my brain is faster." He practices math regularly. So that he can think faster, he exercises, doesn't drink caffeine or alcohol, and avoids foods that are high in sugar or fat. His experience of math is so intense that he also has to take regular time off to rest his brain. Otherwise, he thinks there is a danger that too much math could be bad for his health and his heart.

I occasionally return to some very basic, mathematical thoughts: There are only so many letters in our Roman alphabet. It is then by the power of the math—the infinite (or not strictly infinite, but huge) number of combinations of letters—that we have so many words. But then, further expanding the number of possibilities, truly to infinity, one word (one combination of letters) can have multiple meanings. Further multiplying the number of meanings, even within one given dictionary definition of a word, is the effect of its context, both immediate and larger, which can endow it with, again, an infinite number of subtly differing shades of meaning. Further enriching the single word, within and beyond its contexts, is one’s own personal associations with it, either from one’s reading or from one’s life experiences. And even in one’s own native language, there are a great many words, meanings, and shades of meaning that one simply doesn’t know and may never encounter.

How to live (forty pieces of advice I feel to be helpful but which I don’t always follow) 1. Appreciate happiness when it is there 2. Sip, don’t gulp. 3. Be gentle with yourself. Work less. Sleep more. 4. There is absolutely nothing in the past that you can change. That’s basic physics. 5. Beware of Tuesdays. And Octobers. 6. Kurt Vonnegut was right. “Reading and writing are the most nourishing forms of meditation anyone has so far found.” 7. Listen more than you talk. 8. Don’t feel guilty about being idle. More harm is probably done to the world through work than idleness. But perfect your idleness. Make it mindful. 9. Be aware that you are breathing. 10. Wherever you are, at any moment, try to find something beautiful. A face, a line out of a poem, the clouds out of a window, some graffiti, a wind farm. Beauty cleans the mind. 11. Hate is a pointless emotion to have inside you. It is like eating a scorpion to punish it for stinging you. 12. Go for a run. Then do some yoga. 13. Shower before noon. 14. Look at the sky. Remind yourself of the cosmos. Seek vastness at every opportunity, in order to see the smallness of yourself. 15. Be kind. 16. Understand that thoughts are thoughts. If they are unreasonable, reason with them, even if you have no reason left. You are the observer of your mind, not its victim. 17. Do not watch TV aimlessly. Do not go on social media aimlessly. Always be aware of what you are doing and why you are doing it. Don’t value TV less. Value it more. Then you will watch it less. Unchecked distractions will lead you to distraction. 18. Sit down. Lie down. Be still. Do nothing. Observe. Listen to your mind. Let it do what it does without judging it. Let it go, like Snow Queen in Frozen. 19. Don’t’ worry about things that probably won’t happen. 20. Look at trees. Be near trees. Plant trees. (Trees are great.) 21. Listen to that yoga instructor on YouTube, and “walk as if you are kissing the earth with your feet”. 22. Live. Love. Let go. The three Ls. 23. Alcohol maths. Wine multiplies itself by itself. The more you have, the more you are likely to have. And if it is hard to stop at one glass, it will be impossible at three. Addition is multiplication. 24. Beware of the gap. The gap between where you are and where you want to be. Simply thinking of the gap widens it. And you end up falling through. 25. Read a book without thinking about finishing it. Just read it. Enjoy every word, sentence, and paragraph. Don’t wish for it to end, or for it to never end. 26. No drug in the universe will make you feel better, at the deepest level, than being kind to other people. 27. Listen to what Hamlet – literature’s most famous depressive – told Rosencrantz and Guildenstern. “There is nothing either good or bad, but thinking makes it so.” 28. If someone loves you, let them. Believe in that love. Live for them, even when you feel there is no point. 29. You don’t need the world to understand you. It’s fine. Some people will never really understand things they haven’t experienced. Some will. Be grateful. 30. Jules Verne wrote of the “Living Infinite”. This is the world of love and emotion that is like a “sea”. If we can submerge ourselves in it, we find infinity in ourselves, and the space we need to survive. 31. Three in the morning is never the time to try and sort out your life. 32. Remember that there is nothing weird about you. You are just a human, and everything you do and feel is a natural thing, because we are natural animals. You are nature. You are a hominid ape. You are in the world and the world is in you. Everything connects. 33. Don’t believe in good or bad, or winning and losing, or victory and defeat, or ups and down. At your lowest and your highest, whether you are happy or despairing or calm or angry, there is a kernel of you that stays the same. That is the you that matters.

Before I walked into the door, the room got shades darker as a cloud did a summersault in front of the sun. I turned my head up to the sky and saw Gauss in the glass smirking down at me. In that moment I was reminded of a story about Gauss. 
 When he was in the fifth grade, his teacher wanted some quiet, so he asked his class to add up all the numbers from 1-100. Thinking he had plenty of time to relax, he was shocked that within minutes Gauss had an answer. Gauss had cleverly noticed that the numbers 1 and 100 added up to 101, and 2 and 99 also added up to 101 and on down until you hit 50 and 51. So there are 50 pairs of 101, and a simple multiplication problem by Gauss left his teacher perplexed.
 The recollection of this story reminded me about my own fifth grade experience. Thor was the volunteer at my school for the “Math Superstar” program. After each assignment, stars of various colors signifying degrees of excellence were stuck on all the papers handed in. Like the Olympics, gold was the highest honor. 
 Wendy, the girl who sat next to me, was baffled that no matter how many wrong answers I got (usually all of them), I consistently had gold stars on my papers. She thought Thor was showing a personal bias towards me, but the truth is that I knew where he kept his boxes of stars, so I simply awarded myself what I thought I deserved. Hey, Gauss, how’s that for clever?

There are many things the Chinese do differently from Westerners. There’s the question of extra credit, for example. One time, Lulu came home and told me about a math test she’d just taken. She said she thought it had gone extremely well, which is why she didn’t feel the need to do the extra-credit problems. I was speechless for a second, uncomprehending. “Why not?” I asked. “Why didn’t you do them?” “I didn’t want to miss recess.” A fundamental tenet of being Chinese is that you always do all of the extra credit all of the time. “Why?” asked Lulu, when I explained this to her. For me this was like asking why I should breathe. “None of my friends do it,” Lulu added. “That’s not true,” I said. “I’m 100% sure that Amy and Junno did the extra credit.” Amy and Junno were the Asian kids in Lulu’s class. And I was right about them; Lulu admitted it. “But Rashad and Ian did the extra credit too, and they’re not Asian,” she added. “Aha! So many of your friends did do the extra credit! And I didn’t say only Asians do extra credit. Anyone with good parents knows you have to do the extra credit. I’m in shock, Lulu. What will the teacher think of you? You went to recess instead of doing extra credit?” I was almost in tears. “Extra credit is not extra. It’s just credit. It’s what separates the good students from the bad students." "Aww - recess is so fun," Lulu offered as her final sally. But after that, Lulu, like Sophia. always did the extra credit. Sometimes the girls got more points on extra credit than on the test itself - an absurdity that would never happen in China. Extra credit is one reason that Asian kids get such notoriously good grades in the United States. Rote drilling is another. Once Sophia came in second on a multiplication speed test, which her fifth grade teacher administered every Friday. She lost to a Korean boy named Yoon-seok. Over the next week, I made Sophia do twenty practice tests (of 100 problems each) every night, with me clocking her with a stopwatch. After that, she came in first every time. Poor Yoon-seok. He went back to Korea with his family, but probably not because of the speed test.

Researchers have confirmed what porn producers already know: men tend to get turned on by images depicting an environment in which sperm competition is clearly at play (though few, we imagine, think of it in quite these terms). Images and videos showing one woman with multiple males are far more popular on the Internet and in commercial pornography than those depicting one male with multiple females.14 A quick peek at the online offerings at Adult Video Universe lists over nine hundred titles in the Gangbang genre, but only twenty-seven listed under Reverse Gangbang. You do the math. Why would the males in a species that’s been wearing the shackles of monogamy for 1.9 million years be sexually excited by scenes of groups of men ejaculating with one or two women?

What kind of smart are you?” not “How smart are you?” They might be math smart, word smart, art smart, nature smart, body smart, people smart, self smart, music smart or life smart. (These are from Howard Gardner’s Multiple Intelligences.) It helps to look at children this way and understand how they look at life. Besides

Knowledge of a subject doesn’t necessarily mean you can do anything with it. That would require skill. Likewise, a student can commit something to memory with no knowledge whatsoever. A grade-schooler, for example, might be able to recite the multiplication table perfectly, but still be unable to solve simple math problems. Coming to know something implies the goal of being able to use the knowledge, while being aware of facts or figures does not. Of

Reason #1: Downtime Aids Insights Consider the following excerpt from a 2006 paper that appeared in the journal Science: The scientific literature has emphasized the benefits of conscious deliberation in decision making for hundreds of years… The question addressed here is whether this view is justified. We hypothesize that it is not. Lurking in this bland statement is a bold claim. The authors of this study, led by the Dutch psychologist Ap Dijksterhuis, set out to prove that some decisions are better left to your unconscious mind to untangle. In other words, to actively try to work through these decisions will lead to a worse outcome than loading up the relevant information and then moving on to something else while letting the subconscious layers of your mind mull things over. Dijksterhuis’s team isolated this effect by giving subjects the information needed for a complex decision regarding a car purchase. Half the subjects were told to think through the information and then make the best decision. The other half were distracted by easy puzzles after they read the information, and were then put on the spot to make a decision without having had time to consciously deliberate. The distracted group ended up performing better. Observations from experiments such as this one led Dijksterhuis and his collaborators to introduce unconscious thought theory (UTT)—an attempt to understand the different roles conscious and unconscious deliberation play in decision making. At a high level, this theory proposes that for decisions that require the application of strict rules, the conscious mind must be involved. For example, if you need to do a math calculation, only your conscious mind is able to follow the precise arithmetic rules needed for correctness. On the other hand, for decisions that involve large amounts of information and multiple vague, and perhaps even conflicting, constraints, your unconscious mind is well suited to tackle the issue. UTT hypothesizes that this is due to the fact that these regions of your brain have more neuronal bandwidth available, allowing them to move around more information and sift through more potential solutions than your conscious centers of thinking. Your conscious mind, according to this theory, is like a home computer on which you can run carefully written programs that return correct answers to limited problems, whereas your unconscious mind is like Google’s vast data centers, in which statistical algorithms sift through terabytes of unstructured information, teasing out surprising useful solutions to difficult questions. The implication of this line of research is that providing your conscious brain time to rest enables your unconscious mind to take a shift sorting through your most complex professional challenges. A shutdown habit, therefore, is not necessarily reducing the amount of time you’re engaged in productive work, but is instead diversifying the type of work you deploy.

Contrary to what many well-intentioned people believe, the fact that we have multiple social media platforms today has little effect on spreading genuinely diverse narratives and perspectives. Social media is not only increasingly in the hands of a few billionaires strongly connected to the ruling class (e.g., Meta acquiring some of the most popular and active platforms), but also the fact that social media platforms operate based on carefully designed and manipulated algorithms to promote the viewpoints of the ruling class in what Cathy O’Neil has called ‘weapons of math destruction’, and what Safiya Umoja Noble insightfully calls ‘algorithms of oppression’, which apply not only to racial matters, but extend to every other matter that is potentially at odds with the desires of the ruling class.

I try to teach Magda some things. Since we’re not men and can’t afford. I take my books to her and sit her in a corner in a nice room that smells of rice with milk and cinnamon and teach her things. She does okay in math. She knows multiplication. At first it was, like, 1 × 1, 1 × 2, and it was never past the two, everything equaled two. 5 × 7, 9 × 8, everything was 2. But now she gets it. She gets history. She likes simpler things, made up stories, poems, but she is awful with language. And she can’t spell to save her life.

IN THE SCHOOLS Memorizing multiplication tables may be a seminal school experience, among the few that kids today share with their grandparents. But a Stanford University professor says rapid-fire math drills are also the reason so many children fear and despise the subject. Moreover, the traditional approach to math instruction — memorization, timed testing and the pressure to speedily arrive at answers — may actually damage advanced-level skills by undermining the development of a deeper understanding about the ways numbers work. “There is a common and damaging misconception in mathematics — the idea that strong math students are fast math students,” says Jo Boaler, who teaches math education at the California university and has authored a new paper, “Fluency Without Fear.” In fact, many mathematicians are not speedy calculators, Boaler says. Laurent Schwartz, the French mathematician whose work is considered key to the theory of partial differential equations, wrote that as a student he often felt stupid because he was among the slowest math-thinkers in class.

It is true that Samudramanthan can be interpreted to mean “churning the ocean”. But the root of manthan is manth or math. Which can have multiple meanings in English. Churn is just one of those meanings. Math can also mean stir, agitate or mix. So, if we were to disregard the traditional interpretation of the title itself, it could mean either “stirring the ocean” or “mixing the ocean”.

when I look back on my first two years at McKinsey, a solid 80 percent of my managers’ feedback related to communication skills. They rarely gave me any feedback on my math skills, quantitative analysis skills, spreadsheets, or models.

One thing that went missing from the reporting of Donald’s percentages was some quick math. Donald was in the midst of his I-am-worth-$5-billion-to-$6-billion phase, but by valuing his casino stake at 1 or 2 percent of his net worth he gave himself a personal treasure chest worth no more than $1.7 billion. Still, such is the hypnotic power of the Trumpster that his verbal billions convince people to stop doing multiplication and division.

Here is the rule for deciding which method to use: If a two-digit subtraction problem would require borrowing, then round the second number up (to a multiple of ten). Subtract the rounded number, then add back the difference.

Replacing a worker earning $50,000 a year costs a company about $10,000, or 20 percent of that worker’s yearly pay, according to the Center for American Progress. Replacing a high-level employee can cost multiples of that—as much as two years of salary.

But if you need to bring in multiple stats, you don’t want to mix basket sizes. You want a basket small enough that it feels real and doesn’t make your audience do math, but large enough that multiple stats are directly comparable. 1 in 6 people thought cheesy marshmallow flavor was intriguing, while 4 in 6 thought it was disgusting (note that we changed the basket size above so that the “2 in 3” and the “1 in 6” would live in similar-size baskets, and be easier to compare).

Division and subtraction are not required in a friendship or marriage. Only addition and multiplication of great things.

Compared to students at predominantly white schools, white students who attend diverse K–12 schools achieve better learning outcomes and even higher test scores, particularly in areas such as math and science. Why? Of course, white students at racially diverse schools develop more cultural competency—the ability to collaborate and feel at ease with people from different racial, ethnic, and economic backgrounds—than students who attend segregated schools. But their minds are also improved when it comes to critical thinking and problem solving. Exposure to multiple viewpoints leads to more flexible and creative thinking and greater ability to solve problems.

A parabola opens at a certain direction, allowing for infinitely many points to reside inside the area from which it opens. As a student, I do not like to specialize in a single discipline; specialization seems unfulfilling in my own mind. Hence, the graph of a straight line is not an appropriate analogy to the depths of my curiosity. A line only goes in one direction, and unlike a parabola, a line cannot encase that infinite amount of white space on a coordinate plane—it can only pass through it. Rather than being like a rigid line, I try to be more open to a wider variety of academic subjects. I do admit—a parabola still opens in a certain direction, and of course, my interests are still skewed toward particular subjects. However, the open curve of the parabola can still encompass infinitely many points as the graph extends, the same way my curiosity can still expand to multiple different subjects. This is why I see myself more in the curvaceous parabola than the rigid line.

1 × 3 = 3; 3 × 3 = 9. You can go from one to nine either by adding equal steps of four or multiplying by equal steps of three. So the “multiplication middle” is three, and that is what humans do by default, until we are taught otherwise.

Knowing what the actual differences are (and are not) helps us as parents better recognize our individual children’s strengths and weaknesses. Imagine two moms, both of whom have third-grade daughters struggling in math class. One mom chalks it up to innate differences between boys and girls in math ability and tells her daughter not to worry too much about it. She might even say, “Don’t worry—I wasn’t very good at math either.” The second mom knows that there are no meaningful gender differences in math abilities in elementary school, recognizes that her daughter has a specific problem understanding multiplication, and spends extra time going over math facts at night. Those two girls will have very different academic experiences of math.

Math isn’t about memorizing. It’s about knowing, knowing the language.” She looked at a billboard advertising a pawnshop. A car sped past. “Teachers shouldn’t quiz kids on multiplication tables.” Numbers weren’t something to regurgitate. They were a way to communicate and describe what was happening in the world around them. “Memorizing defeats the whole purpose.

Al-Khwarizmi fell into the taboo that humans refused to fall into throughout their history, not because of their stupidity, nor their lack of attention to the presence of a number here that has an impact, but because they preferred not to deal with it at all unless they fully understood it, they ignored it rather than building the world around them on a wrong frame of reference. So, you have to ask now what if we decided to change the zero and give it its value that we know for sure, which is the unknown. We do not know it, we do not understand it, and not knowing is better than building everything on the wrong frame of reference Any number multiplied by zero equals an unknown The sum of any number with zero equals an unknown The result of any number divided by zero equals an unknown The result of subtracting any number with zero equals an unknown Are you starting to feel the problem and see the size of the unknown that is inside our calculations and our whole life! Infiltrating it without knowing anything about it! The clear is clear, that zero is not only divisible, but also summation, subtraction, and multiplication, because it is unknown, and no matter how much we try to patch the tables to fit the calculations, the division keeps breaking our back and telling us, you are wrong. Despite all this, our strongest strength remains, our winning ball, which has never failed us, is the power of creative adaptation. We are not like viruses, we settle in an environment that we drain and then move to others, nor like animals, we go into an environment and adapt to it and adapt ourselves according to its capabilities. That is why when we hit zero, we got creative and innovated, and decided to change the law of the entire universe, made it a hypothetical effect inspired by our imagination, and built the world on this basis. And the crazy thing is that everything around us is working perfectly. And what is even crazier, is that if we decide to change the effect of zero, so that one multiplied by zero equals twenty, then everything around us will reset, and it will work perfectly as well. Even if we decide to change all the math tables, this universe will mutate to suit our thinking.

The fact of zero He added nonstop: Did you know that zero was not used throughout human history! Until 781 A.D, when it was first embodied and used in arithmetic equations by the Arab scholar Al-Khwarizmi, the founder of algebra. Algorithms took their name from him, and they are algorithmic arithmetic equations that you have to follow as they are and you will inevitably get the result, the inevitable result. And before that, across tens and perhaps hundreds of thousands of years, humans refused to deal with zero. While the first reference to it was in the Sumerian civilization, where inscriptions were found three thousand years ago in Iraq, in which the Sumerians indicated the existence of something before the one, they refused to deal with it, define it and give it any value or effect, they refused to consider it a number. All these civilizations, some of which we are still unable to decipher many of their codes, such as the Pharaonic civilization that refused to deal with zero! We see them as smart enough to build the pyramids with their miraculous geometry and to calculate the orbits of stars and planets with extreme accuracy, but they are very stupid for not defining zero in a way that they can deal with, and use it in arithmetic operations, how strange this really is! But in fact, they did not ignore it, but gave it its true value, and refused to build their civilizations on an unknown and unknown illusion, and on a wrong arithmetical frame of reference. Throughout their history, humans have looked at zero as the unknown, they refused to define it and include it in their calculations and equations, not because it has no effect, but because its true effect is unknown, and remaining unknown is better than giving it a false effect. Like the wrong frame of reference, if you rely on it, you will inevitably get a wrong result, and you will fall into the inevitability of error, and if you ignore it, your chance of getting it right remains. Throughout their history, humans have preferred to ignore zero, not knowing its true impact, while we simply decided to deal with it, and even rely on it. Today we build all our ideas, our civilization, our software, mathematics, physics, everything, on the basis that 1 + 0 equals one, because we need to find the effect of zero so that our equations succeed, and our lives succeed with, but what if 1 + 0 equals infinity?! Why did we ignore the zero in summation, and did not ignore it in multiplication?! 1×0 equals zero, why not one? What is the reason? He answered himself: There is no inevitable reason, we are not forced. Humans have lived throughout their ages without zero, and it did not mean anything to them. Even when we were unable to devise any result that fits our theorems for the quotient of one by zero, then we admitted and said unknown, and ignored it, but we ignored the logic that a thousand pieces of evidence may not prove me right, and one proof that proves me wrong. Not doing our math tables in the case of division, blowing them up completely, and with that, we decided to go ahead and built everything on that foundation. We have separated the arithmetic tables in detail at our will, to fit our calculations, and somehow separate the whole universe around us to fit these tables, despite their obvious flaws. And if we decide that the result of one multiplied by zero is one instead of zero, and we reconstruct the whole world on this basis, what will happen? He answered himself: Nothing, we will also succeed, the world, our software, our thoughts, our dealings, and everything around us will be reset according to the new arithmetic tables. After a few hundred years, humans will no longer be able to understand that one multiplied by zero equals zero, but that it must be one because everything is built on this basis.

Mental arithmetic poses serious problems for the human brain. Nothing ever prepared it for the task of memorizing dozens of intermingled multiplication facts, or of flawlessly executing the ten or fifteen steps of a two-digit subtraction. An innate sense of approximate numerical quantities may well be embedded in our genes; but when faced with exact symbolic calculation, we lack the proper resources. Our brain has to tinker with alternate circuits in order to make up for the lack of a cerebral organ specifically designed for calculation. This tinkering takes a heavy toll. Loss of speed, increased concentration, and frequent errors illuminate the smallness of the mechanisms that our brain contrives in order to "incorporate" arithmetic.

Any student executes tens of elementary calculations daily. Over a lifetime, we must solve more than ten thousand multiplication problems. And yet, our arithmetic memory is at best mediocre. It takes a well-trained young adult considerable time, often more than 1 second, to solve a multiplication such as 3 × 7. Error rates average 10 to 15 percent. On the most difficult problems, such as 8 × 7 or 7 × 9, failure occurs at least once in every four attempts, often following more than 2 seconds of intense reflection.

Mental math has a mixed reputation. Some consider it useless because calculators and computers can solve problems faster, with assured accuracy. Additionally, mental math is not even necessary to get good grades in math or to pursue a professional math career. So what's the point of learning mental math and math tricks anyway? There are many reasons why mental math is still useful. For one, math skills are needed for regular tasks like calculating the tip in a restaurant or comparison shopping to find the best deal. Second, mental math tricks are one of the few times people enjoy talking about math. Third, mental math methods can help students build confidence with math and numbers. Mental math tricks are fun to share. Imagine your friend asks you to multiply 93 and 97, and before

Yet the structure we have built to protect and nurture these children actually does the opposite. Imagine an impoverished six-year-old boy who rarely gets a healthy meal and rarely has parental supervision. He finally goes to school and falls in love with the first person who has ever been there every day for him—his first-grade teacher. She loves and encourages and teaches him. She won’t let the kids bully one another, and she makes sure he gets a good breakfast, lunch, and an after-school snack. Only the weekends are scary. The sixyear-old has a daily routine that includes a committed relationship for the very first time. Life is good; hope is learned. Then the school year ends, and this wonderful teacher says, “Good-bye. You will have a great teacher in second grade.” So the seven-year-old survives the short summer and begins the process all over. But now he has a homeroom teacher, a math and science teacher, a language arts teacher, and a music teacher. Which one is he to fall in love with? Who will fall in love with him? Each of these teachers has dozens of students to care for an hour at a time. And so, at the end of second grade it’s a little less painful to part with his teachers because he never really got to know them. But at least he was physically safe and was fed every day. And so, by the end of third grade, he hardly notices his teacher because he has formed a strong attachment to the friends who move along from class to class with him. They share multiple hours together daily. Instead of taking his signals of proper behavior from a committed adult, since he has none at home or school, he models his life after the future football captain, just as the girls in his class likely emulate the future prom queen. This child from an impoverished culture was taught, in effect, that no adult cares enough to hang out and teach him for more than the 150 hours required to complete a credit. And as he got older, he also learned that the teachers were not quite as able to physically protect him as when he and his classmates were small, and it’s humiliating to have to eat the government-provided free lunch. Even our elementary

But before she read the article in Popular Science she had never been intrigued by mathematics or even thought about the fact that the multiplication table was math. It was something she memorized one afternoon at school, and she never understood why the teacher kept going on about it for the whole year.

One of the great things about mental math is that the calculations can generally be done from either direction, and a certain symmetry generally is present.

It is hard to overstate the beauty of this equation. It combines in one equation what are arguably the most important symbols and operations in mathematics. Along with the operations of addition, multiplication, and exponentiation, you have 0, the additive identity, 1, the multiplicative identity, i, the imaginary unit, and two of the most important mathematical constants, e and π. This equation is also integral to quantum computing. You will see eiθ all over the place in quantum computing, so you better get used to it!

Not everything needs to multiply. Look at Zero. And its impact!
