Almost everyone can do some kind of math. For the same amount of discipline and effort, some people can prove Fermat's Last Theorem, and some people can prove Fermat's Little Theorem. And everyone can coast. Some people can get as far as Calculus without really trying, and some people can only get to basic arithmetic without really trying. But no one can just wander up to a whiteboard and solve a unproven theorem from intuition alone.
