Doing Simple Math in Your Head

Rating:
Summary: One of my all time favorite books
Review: This book is a great way for people to learn how to do simple math problems (arithmetic operations) in their heads. Unlike some other books in the same genre that simply give you gimmicks without explaining how or why they work, W. J. Howard offers tricks that have a solid basis in mathematical logic and explains the rationale. Another problem that many other mental math books have is that they require you to memorize a lot of rules that aren't easily relatable to common sense. Dr. Howard's book, however, only gives you a few rules which are easier to remember because they have a logical basis.

Even if you aren't interested in mental math, this book is a great refresher for those who have forgotten how to do arithmetic without a calculator. So toss out your calculators, sharpen your pencils, and buy this book. You won't regret it.
