That may be true at University, but in Grade 6 & 7 my daughter had to deal with a sexist jock who should never have tried to teach math. He kept stopping the math lessons to go on and on about boys can do ..., girls cannot. She had to constantly correct his bonehead math errors in class. Another teacher at the school organised the Gauss math competition after class sessions. I helped her with the practice exams if she could not intuit the correct algorithm on her own. That was not needed often, she won the Regional Gold medal 3 years in a row.
