For instance in this kind of problem, 769 divided by 47, I think he uses estimation to come to the answer. He ends up with the correct answer with a remainder more quickly than he could write out the problem and i take nearly the same amount of time to check his answer using traditional long division--but i compute very quickly. I've never computed in my head though.
I guess I'm surprised because this is my verbal kid who finds math concepts exciting but not the computation.
