What the hell is “race autonomy”?Africa has never had race autonomy. Mathematics did not start there nor end there. No one ever went to Africa to learn math. If Africans (remember various races, it's never been race autonomous), did "invent" math, it still doesn't mean they understood what they invented. The chinese invented gun powder for eternal life. Frisbees were invented for use in the oven. The list goes on and on. Just because you "invented" something doesn't mean you have the wherewithal to know what it is nor what to do with it. Clearly if so many blacks are fumbling on the most basic of math concepts this point concerning math has been proven if you are trying to imply that all Africans were black (and they weren't) thus share some type of math inheritence.
At least simple arithmetic IS found, the Ishango bone, showing counting, from Africa, and so early that it was before the eurasians had even left (OOA) yet.
Also, it is a fact that ancient Greeks studied math in Egypt, and the tradition of philosophy, math, etc., in Egypt was begun by BLACK people. Africans.
Now whether Pythagoras was always talking to a black Egyptian I can't state with certainty, but nonetheless your statement is false, people did go to Africa to study math.
Yes, inventors know what to do with their inventions, it's just that subsequently others may find other uses for the invention. Egyptians certainly knew how to use math for practical purpose, given the construction of the pyramids and other monuments.
Inner-city blacks don't do well in math class so you think that proves something? Poverty screws up education for many ethnic groups. It's not a black thing.
Explain the blacks I know who are engineers. Lots of math involved...
