I'm really curious about this myself. My first instinct is that it's a crock, but I'm willing to give it the benefit of a doubt. It's always possible to come up with a new way of doing things if you are creative and have an open mind that is not bounded by prior knowledge. Trig is/was a pain in the butt, Geometry was really easy, Algebra, not too bad, and calc was actually not too bad.

LubeMaster, you may want to look into teaching your son to use an abacus. I've always been more into math and science than the other subjects. I've recently begun to teach myself to use an abacus (actually a soroban which is the Japanese version). I wish I had learned it years ago. I'd recommend it to anyone with kids. It teaches a new way to look at addition/subtraction and multiplication/division. You can even takes square and cube roots with them.

Here are several links with info.
