Have trouble reading that?

When you don't understand a language,
you don't have access to the ideas in that language,
even when the ideas are simple.

"the PURPLE book"

Some people have trouble with math.
Often, it's not because the ideas are difficult, but because they are being presented in a foreign language.

This book teaches the language of math.
It explores ideas that are central to ALL of mathematics.
You don't need any computational skill beyond arithmetic with numbers like 1, 2, and 3.

It's a quick read.
Do it!
Math will make more sense!

Use it for any math class, from junior high school through college-level, or for self-enrichment at any age.
