Review # 1 was written on 2013-02-05 00:00:00 Ashley Stockdale Oh, yeah - where was this book when I was a boy?! I own a half a dozen or more speed math/mental math/math shortcuts book, but this is my favorite. A really cool layout, and great explanations. For example, breaking into factors before multiplying: 16 x 35 = 16 x (5 x 7) = (16 x 5) x 7 = 80 x 7 = 560 or 16 x 35 = (2 x 8) x 35 = (2 x 35) x 8 = 70 x 8 = 560 Anyway, it's a small book - 130 p., with index, printed and bound in landscape mode, with good tips on how to simplify numbers in your head (or on paper, if you prefer).

Review # 2 was written on 2016-03-15 00:00:00 Jonathan Gianguzzo I didn't finish reading this book, but I purchased it. It shows simple ways of accomplishing addition, subtraction, multiplication and division. Ways that were obvious once I read about them, but which never occurred to me in the past. I used some of the tricks to develop a math program to "catch up" my future math students. Great book.
