Summary: Very well written book
Comment: This book is very well written. I have always done well in math classes. I never really enjoyed mathematics though. This book makes what seems impossible possible. If you ever wanted to be able to square a number like 72 in your head in seconds this is the book for you.

Summary: One very practical chapter; The Art of 'Guesstimation' !!!
Comment: I'm neither interested in squaring three-digit numbers in my head nor in doing mathematical magic. I'm only interested in practical mental math. I did buy this book for chapter 5; *** Good Enough; The Art of 'Guesstimation' ***. I've been doing guesstimations for many years intuitively, not very structured. This fine chapter teaches beginners the art of guesstimation while experts can go back to the basics and hone their skills while they might discover something new ... I did do so with approximating years needed for trippling an investment given interest rates of X% p.a.

Summary: Does what it says it will
Comment: I have always been good at math, but I still found a lot of the tricks in this book new and handy. Most of these tricks don't require that you are good at math - my husband was even able to do them!
