4.0 out of 5 stars Title Somewhat Deceptive, October 19, 2001

By	Charles M. Proctor, Jr. (Silver Spring, MD USA) - See all my reviews

I am a long retired teacher and supervisor of mathematics. In addition to having taught math for many years, I have also written and published materials covering the same subject. I am now using this book with an eight year-old math whiz and find it valuable to introduce him to rapid calculation and then an analysis of why it works (largely based on our place-value system of numbers. The various methods are interesting but most of them are not very practical for everyday calculation since most are special cases rather than general applications. For successful use they also require instant recall of the basic number facts and there is no hint as to how this can be accomplished. Barring that prior requirement not many math phobes will become highly skilled arithmeticians in 30 days using this or any other book.

5.0 out of 5 stars Cool Tricks, May 17, 2000

By	D. E Sweet "P.Diddy" (La Jolla, CA. USA) - See all my reviews (REAL NAME)

This book has some very cool tricks. It really helps out a lot on tests. It is fun to show my dad them (he is really interested in math). In math class we are reading this book and doing the problems. I don't see how Mr. Julius figured out these tricks. You should get this book!

5.0 out of 5 stars A Entertaining Book for Anyone who Wants to Make Quick Calculations - Without a Calculator !!, August 1, 2006

By	David De Sousa "The Automation and Control Guy" - See all my reviews (TOP 1000 REVIEWER)

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.
