If math is binah then why is there a very large societal stereotype of men being good at math and women being not as good at math? Wouldn't that mean then that men are good at binah consciousness? This is why I don't know why people say that women have binah. Don't a lot of men have binah?

To be more exact regarding your previous question, "bina" is unquestionably involved in math. Nevertheless, math is more "da'at" which includes chochma and bina together. Men and women have chochma, bina and da'at, but there are obviously different levels regarding each individual.
