Title Somewhat Deceptive,
This review is from: Rapid Math Tricks & Tips: 30 Days to Number Power (Paperback)
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.

new ways to think about math,
By Len (Connecticut USA) - See all my reviews
This review is from: Rapid Math Tricks & Tips: 30 Days to Number Power (Paperback)
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.
