Mathematics is not a parlor trick. It's a purely cognitive and abstract system which can be infinitely recursed upon itself to learn ever more which, seemingly by good fortune, happens to map onto many things in the real world. Once one learns addition, the concept of multiplication comes naturally. As does subtraction, at which point you quickly end up on the eery domain of negative numbers, and so on.

To see how silly these things are imagine somebody claiming to have taught mathematics to one of these numberless tribes by training them to pick a larger group of items when it's blue, and pick a smaller group of items when it's yellow. Somebody claiming that is teaching them math would obviously be looked at like an idiot. It's a circus trick - and a rather apt reflection of what passes for research now a days.
