 Some neat tricks May 29, 2008
I love this book! Well... At least parts of it. But those parts are enough to give it a five star rating. You will learn quite a few tricks that will speed up you head calculations enormously. However, they only applies to certain calculations, so while you sometimes will impress your friends and colleagues, you will still find problems that takes as long as before.

In an easy to read and entertaining way the author shows you tricks and shortcuts that will enable you to perform quick arithmetic calculations. Following the book you will learn two tricks or methods, each one illustrated with step-by-step explanations. There are about 2000 exercises that will help you master arithmetic.
Through easy and fun techniques you will be able to perform seemingly difficult problems in addition, subtraction, multiplication, and division, maybe even faster than if you were to enter the number in a calculator.
Once you start reading this book, you will be hooked with it, and with your recent ability to make fast simple calculations. But lets keep it real, this is just a collection of tricks and shortcuts for arithmetic operations (+, -, x, /) you won't become an expert mathematician, but you will enjoy math a lot more.
new ways to think about math November 30, 2005
5 out of 6 found this review helpful
I read this book about once a year. It turns arithmatic inside-out, showing quick tricks to do calculations in your head, or ways to transpose number problems to view them in new ways that make them easier to solve. For example, using the power of reciprocals, multiplying by 5 is equivalent to dividing by 2 and moving the decimal point to the right spot through a test of reasonableness. I apply many of the tips in this book regulaly in my job during the day, and the more times I review the book the more they've become intuitive. I highly recommend for anyone interested in math or numbers, or deals regularly with simple math problems.

 Examples of math that should not be done November 16, 2002
14 out of 45 found this review helpful
This book is designed to do something that simply should not be done. While the mathematical inadequacies of the American public are conceded here, teaching people sixty tricks is hardly the solution. Furthermore, if someone cannot divide by 4 in the normal way, how is it possible that they will learn to do it by dividing by 2 twice? The rules of division are the same in both cases. If someone understands the rules of arithmetic, then all of these tricks are superfluous.
Even if these sixty special cases are thoroughly learned, that is, memorized, the amount of mathematics digested will be minimal, as no generalizations are made. For example, one of the tricks is the rapid multiplication of any one- or two-digit number by 101. But the reasons for this are never explained, so the end result is the reader knows only one particular operation on a small set of numbers.
The accountant or bookkeeper that wishes to increase their ability to compute on the fly may find this book of interest. But, to all others, the message is simple and direct, spend your time learning the general rules of arithmetic!...
