The Speed Math Bible written by Yamada Takumi, with the special collaboration of Danilo Lapegna Transform your brain into an electronic calculator and master the mathematical strategies to triumph in every challenge! "The 101 bibles" series I - The Speed Math Bible I'm quite sure we could all agree about a fact: the traditional way to teach mathematics has a lot of structural problems, and in most of cases it doesn't really help students to get confident with the subject. In fact, too many students finish their schooling still having a real "mathematical illiteracy", united with a burning hatred of everything concerning numbers and operations. In particular, talking about classic method of teaching mathematics, I'm strongly of the opinion that: It's really poor incentive for individual creativity: in fact, too many times school will teach you that the proper method for performing a set of calculations is "rigidly" one, and that everything should always be made in the same way. This obviously can't do much more than boring every student and generating the feeling that the matter itself, rather than improving one's mental skills, actually shrinks them, gradually transforming him/her into something that's more similar to an industrial machine. This book, however, is designed to go far beyond this restricted vision and will teach you that the classic approach is not the only possible approach and that every set of mathematical calculations can be transformed into a deeply creative challenge. The idea of mathematical "trick" is unjustly "demonised": very few people know that they could perform very complex calculations just by using extraordinarily rapid and effective numerical tricks. And although it's widely accepted that learning the right balance between tricks and rigour, creativity and structure, quick solutions and harder solutions would be ideal for any student, schools usually continue to prefer following a "complexity at all costs" that of course does not nothing but alienating people from the matter. It's promoted very little self-expression: too many people feel that they have "nothing to share" with some mathematical concepts even because the rigidity of the taught method prevents everyone from expressing himself according to his talent, his wishes and his natural predispositions. But this book presents a completely different approach, since everything among its pages will be deeply self-expression oriented, and the methods shown here will teach you not just one, unquestionable method to solve everything, but will give you the freedom to act according to what you feel to be easier and more compatible with your natural attitude. It's promoted very little curiosity and "researching spirit": math, as taught from some very bad teachers, is presented as a grey and squared world, made of endless repetitions and very few interesting things. But thanks to this book you will start an original journey through the singularities and the curiosities of the numbers world and you'll soon find out how many interesting and beautiful things are hidden into its deep harmony. They speak very little about the real utility of mathematics: beyond the ability to calculate your restaurant bill in an instant, the enormous advantage you will gain in every official test or exam, or the awesome progression of your logical and deductive faculties, you will discover that mathematics has extraordinary strategic and creative applications that will help you very often in your everyday challenges, giving you that extra oomph in the administration of your personal finance, your work, your studies, your health, your self-confidence and your strategic intelligence when dealing with any kind of challenge. Math is also vital engine and fuel for every little technological wonder in the modern world. Computers and tablets could never exist today if two mathematicians like John von Neumann and Alan Turing didn't write the mathematical principles behind the first calculators. Internet would never have existed if no one had developed the mathematical principles the networks theory is based on. And the search engines and social networks could never be born without the equations and algorithms allowing each user to track, retrieve and organize documents, web pages and profiles directly from a set of chaotic data. Moreover, the inventors of Google and revolutionaries of the modern world, Larry Page and Sergey Brin, are both graduates in mathematics. What I'm trying to tell with this? Well, I'm not sure that every reader of this book will end up founding the new Google, but I'm sure that a greater mathematics competence in a world tuned on these frequencies can help each of us to be more a protagonist and less a bare spectator of it. In other words, this book will not simply be a set of strategies for impressing someone or increasing your academic performance, but will let you start a journey through a pleasant and intriguing path of personal growth, along which you'll learn to be more effective, creative, confident and, why not, more intelligent. In addition to that, I would like to give you a last advice: do not immediately try to learn every method explained here, but go slowly, make notes, select the techniques you like most and train yourself calmly and always taking your time. This will help your mind to learn everything with much more ease and less effort. Enough said: now I can't do anything but wishing you all the best and, of course, to enjoy your reading! Yamada Takumi About the authors: Yamada Takumi and Danilo Lapegna are two Software Engineers working in London as software developers and freelance writers. Their series of books, "The 101 bibles", has been a great sales success in the self-publishing sector in Italy, engaging thousands of electronic readers even in a moment of economic instability for the Italian market. Now they're constantly expanding their series with new books about personal and professional self-development and their work represents an important reference point in the market. For any kind of questions, help requests or, most of all, feedbacks, you can write them at "The moving power of mathematical invention is not reasoning, but imagination." (A De Morgan) II - 5 mathematical strategies that will seriously improve your life We constantly count and make measurements in our everyday life: how many hours must we sleep to feel really refreshed, what's our ideal body fat percentage, how much time do we need to finish examining those documents, after how many miles the gas tank of our car will be empty ... these are all examples of everyday problems we constantly have to deal with, and that obviously would require a solution as more effective as possible. At the same time, however, we too often evaluate the factors involved in our problems from a purely qualitative point of view rather than a quantitative one, giving them purely empirical solutions. That is, for example, instead of trying to understand the proper amount of sleeping hours for our body, we too often try to sleep enough to feel relatively fit. Rather than calculating our body fat percentage and adjusting our diet accordingly, we prefer some kind of homemade diet that does not really pay attention to our real physiological needs. And we do that despite it is intuitive that addressing these issues from a quantitative point of view, and so measuring, evaluating, calculating the quantities involved, would offer a greater efficiency to our actions, and so would give us the ability to produce much more with many less expenses in terms of time, money and resources. Wait: this does not mean that you should run into some weird obsession for rational assessments or for measuring every single aspect of reality. Your existence of course needs even impulsively done actions, lessons learnt from your mistakes and the coexistence with the inevitable unknown. However, when you actually feel the need to get more results in a specific field, a stronger mathematical "grip" on it could be a great strategy to enhance your personal improvement. After all, the most successful companies are exactly those doing the best in retrieving and analysing data about the consequences of their behaviour. But how could we do that? Here's some advices we could follow for the purpose: Play giving marks more often. No, this has nothing to do with school. If, for example, you really enjoy doing something, like, I don't know, eating a particular type of food or going traveling somewhere, try giving to these actions, or to the advantage you get from doing them, a mark. From 0 to 10, from 0 to 100, it doesn't matter! The point is playing making quantitative concepts out of qualitative ones, and starting making better analysis on their basis. For example, if dedicating yourself to jogging in the morning has for you a higher mark than going to gym, you could simply start to decide to ... go jogging more often! Quantity in most of cases helps you to better focus on the most important things, and cleans your thoughts from the unnecessary stuff! Try to make measurements where nobody else would do it. "Not everything that can be counted really counts, and not everything that counts can be really counted", said Albert Einstein. This phrase not only confirms what I earlier said about the fact that mathematics and calculations sometimes must simply be put aside (luckily), but can help us to understand that, too much often, the most commonly used measurement systems can deceive us, and can divert our attention from the things that really matter. An example I love doing about this is in the school report cards: their obvious purpose should be giving the measurement of the performance of a student, but we often forget that, on the other side, there could be a teacher that simply has an awful teaching method. And that's where we should start to "make measurements" where nobody else would do it: letting the students evaluate the quality and the goodness of their teacher's work could push everybody into doing better his/her work, and consequently into producing better results for everybody. Making measurements, evaluating, focusing on the things that other people tend to ignore, gives you that extra oomph that will produce a significant advantage in any kind of situation! Increase the quantity and improve the quality of your measurement instruments. Imagine: it's a lazy evening and you decide to go watching a movie to the cinema. Now, you have to decide which movie buying the tickets for, but you're hesitating between that new action movie with a lot of old celebrities and that new horror Japanese movie about a dead woman who comes back from the grave. Now you could take your smartphone, read the movie reviews from some famous website and simply choose the movie with the highest rate. But of course you would better estimate the quality of those movies after increasing the quantity of your measurement instruments and, for example, reading movie ratings from many different websites instead than from only one of them. Now there is a concept that can really come in handy: the mathematical mean that, although is quite widely known, we'll explain in a few words, just to make sure that everybody knows what are we talking about. If you have multiple quantities, multiple measurements, multiple values (ex. 3, 4 and 5 stars rating for a movie on three different websites), you can sum those numbers (ex. 3 + 4 + 5 = 12) and then divide the result by the number of values you considered (three ratings in this case, so 12 / 3 = 4). This will give you the mean of those quantities, which is universally considered as a very precious value since, as in the measurements theory, as in the probability one, it's said to be very close to the "real" value of something (if a real value can philosophically or scientifically exist, of course). But now, let's add something and let's talk about quality of measurement instruments: how many times happened that a multi-award winning movie just left you asleep in your chair?
