Secrets of Mental Math: The Mathemagician's Guide to Lightning Calculation and Amazing Math Tricks Reviews

Summary: Great for any age and skill level
Comment: I recently purchased this book after a stranger in a bookstore suggested it. I'm already impressed. There are quite a few 'speed math' books out there, but this one is easily accessible to everyone and is intended to help with everyday life. I'm fairly advanced in college-level math and I intuitively knew some of the suggestions in the book, but it has helped me brush up, learn new things, and most of all learn how to do it BETTER.

I highly recommend this book to students because it is a tremendous help to know how to perform quick math in your head. Even if you have a calculator, just knowing what to expect for the outcome helps you perform faster and serves as a double-check when you need it. And knowing how to do math quickly is essential on a standardized test like the SAT. Even if you know how to do all the problems correctly, the time limit can cripple you--so do yourself a favor and get this book.

Some of the topics covered in this book include 'basic' to 'advanced' multiplication, mental division, guesstimation, calculating the day of the week, and memorizing numbers through mnemonics.

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!

No one is too set in their ways to find the magic within its pages:)
