Summary: This is way better than his first rapid math book!
Comment: I have to admit I hated the first rapid math book he wrote.Besides that,this book is way more better than the first.I gave it three stars instead of five because you have to memorize all of the addition ,subtraction ,mutiplication, and division tables.I wish he would teach rapid math tricks to remember your tables.You'll keep saying to yourself "If only I knew my facts this trick would be alot easier." I hope he reads this.

Summary: Title Somewhat Deceptive
Comment: 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.

Summary: Cool Tricks
Comment: 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!
