Yeah, I was terrible at math in college. To be honest, I was terrible at everything, but math especially. It wasn't until a few years ago that I started to take an interest and go back and learn the things that I struggled with then.
Ten years seemed sufficient enough for me to place enough value on math that I was able to overcome whatever my original deficiency was. I'm all for finding a way to teach math that helps others in the same way.
This could be a great candidate for a multimedia textbook... 10-minute videos + notes + interactive proofs?
Virtually nobody knows what "math" actually is before college. Even in college I suspect the number is still low. If nothing else his project has the potential to fix that.
