First, let me say I've always hated math. So liking this book was an unexpected surprise. I picked it up at a yard sale for a quarter because I liked the illustrations. I didn't know I would learn so much. Periodically, I'd just stop and say...whoa, that's really cool.

Robert, a boy who hates math, meets a number devil in his dreams at night, and has practical experiences about how numbers work in a magical way.

This book is fiction, but it teaches basic math concepts and in a logical and fun manner. You might not even realize you're learning at the time. I learned about zero and how it's not really a number and why, about prime numbers (called prima donna numbers in the book), infinite numbers, Fibonacci numbers (that was really cool), square roots (rutabaga numbers) triangle numbers in patterns, etc. Numbers = magic.
