Mental Mathematics

Math is not only the game of numbers but also the language of nature. As a matter of fact, it has been established through research that the more we understand our universe, the more we discover interesting mathematical connections. For instance, flowers have spirals that are carefully lined up in a special sequence of numbers commonly referred to as Fibonacci numbers. This sequence can be studied, understood, and generated.

This book shows how to do mental math with methods designed to simplify basic math for fast and easy calculations. Basic operations covered are addition, subtraction, multiplication, and square roots. Example problems are completed with answers for practice and improving your memory. Large and small number problems are included with real life sample problems. Exact and fast approximation techniques are shown.

Will you pay more for a $19.99 shirt with a 20 percent discount or a $24.99 shirt with a 30 percent discount? The truth is, most of the math you find yourself doing on a day to day basis it's usually done in your head, that's why improving your mental math skills is always useful. If you’ve grown up hating math, that’s probably because you’ve been taught with the wrong approach. Math can help you calculate a discount on the fly, easily multiply big numbers, or quickly figure out how much dough packs you’ll need to make 50 cookies if one pack will be enough for 20.

Mental math is the ability to solve math problems in your head, without the need to write or use a calculator. And it has all of the benefits implied above and much more. Preliminary studies have even shown that mental math can improve your emotional health as well.

For two decades, John Mighton has developed strategies for fostering intellectual potential in all children through learning math. Math, Mighton says, provides us with mental tools of incredible power. When we learn math we learn to see patterns, to think logically and systematically, to draw analogies, to perceive risk, to understand cause and effect - among many other critical skills. Yet we tolerate and in fact expect a vast performance gap in math among students and live in a world where many adults aren't equipped with these crucial tools.

Join The Math Dude, Jason Marshall, as he leads you through the tricky journey of mastering addition, subtraction, multiplication, division, AND percentages in your head. Whether you’re calculating the tip on a $76.85 meal or you’re frantically doing mental math in a business meeting—Math Dude has got you covered.

No matter how simple it may be, solving mathematical equations can be a challenge for quite a number of persons Through his book titled Secret of Mental Math Arithmetic: 70 Secrets to Super Speed Calculation Amazing Math Tricks, Jason Scotts seeks to provide the solution to those mathematical problems.

In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm.

Research shows that people often wildly misunderstand the state of the world, regardless of age, sex, or education. And though the internet brings us unprecedented access to information, there's little evidence we're any better informed because of it. We may blame cognitive bias or fake news, but neither tells the complete story. Bobby Duffy draws on his research into public perception, offering a sweeping account of the stubborn problem of human delusion: how society breeds it, why it will never go away, and what our misperceptions say about what we really believe.
