Arithmetricks: 50 Easy Ways to Add, Subtract, Multiply, and Divide Without a Calculator

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

She loves math now!

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.

A must for math teachers!!!

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.
