I plan on using this book to enhance my students mental math abilities. This book is a great way to do the mental math and focus on that higher order thinking. This book is organized well, and is well-suited for classroom use. There were many tricks that I didn't even know existed and everything is still based on basic math. This can work from the slowest to the most advanced learner.

My 9 year old had always loved math but this year we moved and neither of us liked the math curriculum the new school used. She began hating math! We began homeschool (there were other problems too) BUT she continued fighting with the math work. I purchased this book and after only 4 lessons she's hooked on math again! She loves the tricks and VOLUNTARILY makes up her own problems to solve! She's already seeing how the "tricks" help her in her "normal" math work.

It is plainly a superb book, I'm amzaed that the mathematical tricks in this books are so useful in everyday life. It liberates one from growing dependency on calculators. It's a treat now to be able to do complex multiplication & division calculations in ones mind. Regular practise of tricks is a must for max benefits.

We got this book from the library to supplement my 5th grade daughter's homeschool math, and I've decided to purchase it. My undergraduate is in Physics, so I've done my share of arithmetic. What is so cool about this book is that it contains every trick I've ever come up with or figured out, plus a whole lot of others that I wish I'd known.

Learning these tricks is so much cooler than using a calculator!

This book is amazing and a must have for every student. It breaks down every mathmatical process in easy and understandable soultions that will leave you saying "Oh yeah I see it now" This was definately a 10 out 0f 10.

The math tricks are very cool and easy to understand. This book is awsome for people of all ages.

In Texas, U of Texas sponsors "UIL" which is "University Interscholastic League" -- a competition among public schools in several areas. One of these is "number sense", which is doing quick-thinking arithmetic in your head, or with assitance of a scratch sheet.

This book is the best one for training in that. I , after growing up, first had "Short-Cut Math" which is quite good, but this one does it one batter. I have 3 other books on the same subject, and this is the best of the five, althougn one which is quite cutesy might be a good starter for someone having a lot of trouble and needing some "mneumonic story aids".

This is formula manipulation, which in high school [ and even junior high now ] is called algebra. That't what's behind it all -- so kids that learn this have a leg-up on that field later on.

One other crucial fact for usage in "standardized testing" -- this is great for quickly "ball park estimating" the answers to multiple choice questions, which come up in word problems and chemistry in particular.

These Math tricks are great! I wish I learned these tricks when I was younger. I feel so smart for multiplying two double digit numbers together without using a calculator.

This is a great book, it really helps with math. There are alot of short cuts and secrets (hints) to help with solving problems. It is worth the money.

Purchased this book for my math loving 8 year old. He absolutely loves to show off his new math tricks which are easy to learn and well described. I would highly recommend this to all the "math loving" adults and children alike.
