Description
Excerpted from the website:
- You find a math problem in a book, or maybe on a contest, or maybe your teacher tells you the problem. You work on it for a half-hour. Then another half-hour. It bugs you and bugs you because you know that other kid who wins all the trophies knows how to do the problem.
