Mental Math: Tricks To Become A Human Calculator


Abhishek V.R. - 2017
    Just read this till the end You don’t have to buy this book. Just read this till end & you will learn something that will change the way you do math forever. Warning: I am revealing this secret only to the first set of readers who will buy this book & plan to put this secret back inside the book once I have enough sales. So read this until the very end while you still can.School taught you the wrong way to do mathThe way you were taught to do math, uses a lot of working memory. Working memory is the short term memory used to complete a mental task. You struggle because trying to do mental math the way you were taught in school, overloads your working memory. Let me show you what I mean with an example:Try to multiply the 73201 x 3. To do this you multiply the following:1 x 3 =0 x 3 =2 x 3 =3 x 3 =7 x 3 =This wasn’t hard, & it might have taken you just seconds to multiply the individual numbers. However, to get the final answer, you need to remember every single digit you calculated to put them back together. It takes effort to get the answer because you spend time trying to recall the numbers you already calculated. Math would be easier to do in your head if you didn’t have to remember so many numbers. Imagine when you tried to multiply 73201 x 3, if you could have come up with the answer, in the time it took you to multiply the individual numbers. Wouldn’t you have solved the problem faster than the time it would have taken you to punch in the numbers inside a calculator? Do the opposite of what you were taught in schoolThe secret of doing mental math is to calculate from left to right instead of from right to left. This is the opposite of what you were taught in school. This works so well because it frees your working memory almost completely. It is called the LR Method where LR stands for Left to Right.Lets try to do the earlier example where we multiplied 73201 x 3. This time multiply from left to right, so we get:7 x 3 = 213 x 3 = 93 x 2 = 60 x 3 = 03 x 1 = 3Notice that you started to call out the answer before you even finished the whole multiplication problem. You don’t have to remember a thing to recall & use later. So you end up doing math a lot faster. The Smart ChoiceYou could use what you learnt & apply it to solve math in the future. This might not be easy, because we just scratched the surface. I've already done the work for you. Why try to reinvent the wheel, when there is already a proven & tested system you can immediately apply.

The Calculus Direct


John Weiss - 2009
    The calculus is not a hard subject and I prove this through an easy to read and obvious approach spanning only 100 pages. I have written this book with the following type of student in mind; the non-traditional student returning to college after a long break, a notoriously weak student in math who just needs to get past calculus to obtain a degree, and the garage tinkerer who wishes to understand a little more about the technical subjects. This book is meant to address the many fundamental thought-blocks that keep the average 'mathaphobe' (or just an interested person who doesn't have the time to enroll in a course) from excelling in mathematics in a clear and concise manner. It is my sincerest hope that this book helps you with your needs.Show more Show less

Footballistics


James Coventry - 2018
    The nature of football continually changes, which means its analysis must also keep pace. This book is for students, thinkers, and theorists of the game.'Ted Hopkins - Carlton premiership player, author, and co-founder of Champion Data. Australian Rules football has been described as the most data-rich sport on Earth. Every time and everywhere an AFL side takes to the field, it is shadowed by an army of statisticians and number crunchers. The information they gather has become the sport's new language and currency. ABC journalist James Coventry, author of the acclaimed Time and Space, has joined forces with a group of razor-sharp analysts to decipher the data, and to use it to question some of football's long-held truisms. Do umpires really favour the home side? Has goal kicking accuracy deteriorated? Is Geelong the true master of the draft? Are blonds unfairly favoured in Brownlow medal voting? And are Victorians the most passionate fans? Through a blend of entertaining storytelling and expert analysis, this book will answer more questions about footy than you ever thought to ask. Praise for Time and Space:'Brilliant, masterful' - The Guardian'Arguably one of the most important books yet written on Australian Rules football.' - Inside History'Should find its way into the hands of every coach.' - AFL Record

The Joy of x: A Guided Tour of Math, from One to Infinity


Steven H. Strogatz - 2012
    do it? How should you flip your mattress to get the maximum wear out of it? How does Google search the Internet? How many people should you date before settling down? Believe it or not, math plays a crucial role in answering all of these questions and more.Math underpins everything in the cosmos, including us, yet too few of us understand this universal language well enough to revel in its wisdom, its beauty — and its joy. This deeply enlightening, vastly entertaining volume translates math in a way that is at once intelligible and thrilling. Each trenchant chapter of The Joy of x offers an “aha!” moment, starting with why numbers are so helpful, and progressing through the wondrous truths implicit in π, the Pythagorean theorem, irrational numbers, fat tails, even the rigors and surprising charms of calculus. Showing why he has won awards as a professor at Cornell and garnered extensive praise for his articles about math for the New York Times, Strogatz presumes of his readers only curiosity and common sense. And he rewards them with clear, ingenious, and often funny explanations of the most vital and exciting principles of his discipline.Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

In Pursuit of the Unknown: 17 Equations That Changed the World


Ian Stewart - 2012
    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

How Numbers Work: Discover the Strange and Beautiful World of Mathematics (New Scientist Instant Expert)


New Scientist - 2018
    No, hang on, let's make this interesting. Between zero and infinity. Even if you stick to the whole numbers, there are a lot to choose from - an infinite number in fact. Throw in decimal fractions and infinity suddenly gets an awful lot bigger (is that even possible?) And then there are the negative numbers, the imaginary numbers, the irrational numbers like pi which never end. It literally never ends.The world of numbers is indeed strange and beautiful. Among its inhabitants are some really notable characters - pi, e, the "imaginary" number i and the famous golden ratio to name just a few. Prime numbers occupy a special status. Zero is very odd indeed: is it a number, or isn't it?How Numbers Work takes a tour of this mind-blowing but beautiful realm of numbers and the mathematical rules that connect them. Not only that, but take a crash course on the biggest unsolved problems that keep mathematicians up at night, find out about the strange and unexpected ways mathematics influences our everyday lives, and discover the incredible connection between numbers and reality itself. ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.

Why Not Kill Her: A Juror's Perspective: The Jodi Arias Death Penalty Retrial


Paul A. Sanders Jr. - 2015
    The killer went to great lengths to cover up her crime including sending his grandmother flowers, going to the memorial service, driving by the victim’s house and calling the lead investigator, Detective Esteban Flores. This incident took place in a suburb of Phoenix, Arizona. It would be five years before this case of capital murder would be put in front of a jury to decide the fate of Jodi Arias although the fate of Travis Alexander had been set in stone. Was she a cold, calculating murderess or was she a victim of extreme domestic violence at the hands of an abusive boyfriend? The first jury was left to decide in 2013. It was the most watched trial of the century. The jury decided that Jodi Arias was guilty of first-degree murder with cruel and heinous circumstances which qualified her for the death penalty. The jury could not reach a decision in the penalty phase and justice was delayed. A new jury, drawn from a pool of four hundred people, was drawn for the highly anticipated retrial of Jodi Arias. On October 21, 2014, a jury of nineteen was given the responsibility of deciding whether Jodi Arias should live or die for her crime. So began a retrial that would last almost five months with Juan Martinez and Detective Flores representing the State of Arizona and the return of Kirk Nurmi and Jennifer Willmott speaking to the defense of the convicted killer. The journey will walk the reader through the meticulous actions of the courtroom and extend to an appellate court, a municipal court and a day in the in the original courthouse in phoenix, Arizona. The trial speaks toward the long arm of the law and the implications of decisions made daily. With the help of former jurors of the Jodi Arias death penalty retrial, the reader will step into the jury box when Jodi Arias was on the witness stand and reach a climax when the reader accompanies the jury foreman into the deliberation room as the jury decides the fate of the defendant. “The lambs to the law were now executors of the law. It was humbling, intimidating and powerful at the same time. It was also the time that the jurors’ souls would be tested for truths and experiences that would mark many discussions in the deliberation room. The jury would remember Travis Alexander and what was done to him.” Why Not Kill her is the suspenseful follow-up to the authors first book, Brain Damage: A Juror’s Tale, the true story of being a death penalty juror on the case of Marissa DeVault and the brutal killing of Dale Harrell. The third revised edition is now available in honor of Dale Harrell. Take a journey into the life of Travis Alexander and a search for truth and justice. Somehow, Lady Justice will wield her sword and the end of a seven year saga would be realized but in no way that anyone could have anticipated.

"He Killed Our Janny:" A Family's Search for the Truth


Sherrie Lueder - 2011
    But behind the closed doors was a story of drugs, orgies, physical and sexual assault, and constant fear...Book voyeurs who are able to tackle tough subject matter will love this tale." --Kim Cantrell True Crime Book Reviews~~~~~~~~~~BESTSELLING, AWARD WINNING AUTHOR, SHERRIE LUEDER'S GRIPPING TRUE STORY OF A SON AND DAUGHTER'S PAINFUL MEMORIES AND FIGHT FOR SURVIVAL WHILE GROWING UP IN AN ABUSIVE HOME IN THE SUBURBS OF DENVER--THEIR OWN INVESTIGATION INTO THEIR MOTHER'S MYSTERIOUS DEATH--AND RELENTLESS QUEST FOR JUSTICE. This book is the first to explore the mysterious death of Janyce "Janny" Hansen, a former top model from Denver, Colorado. She, along with her husband and children, live in an upscale home in the suburbs. The community sees an affluent, glamorous family. The reality is far different. An abused wife who can't let go. A husband who beats and sexually assaults his adopted children--while running gambling and prostitution businesses from their home. In the early morning hours of September 21, 1984, her husband returns home to discover her lifeless body in his Mercedes convertible parked in the garage--or so he says. Her family is led to believe she committed suicide. Now, 25 years later, her son and daughter set out to prove their mother was killed by her husband, a successful real estate developer rumored to have strong ties to city officials and underworld crime. Many believe the investigation into Janny's death was a cover-up--starting with the coroner's office--and that her husband got away with murder. As their investigation continues, they are led to believe their suspicions are true. Especially, since evidence increases almost daily and points to only one killer--Janny's husband.
