That is because math is probably the only subject that is taught by math education idiots and not by mathematicians. The math education people cannot do math and can only teach what is on a lesson plan for it and not understand the mathematics themselves. On rare occasion at a university a mathematics professor who is not math education teaches a math class that can only be taught by a mathematician.
My twin brother refused cataract surgery and special education so the teachers and coaches would pause the game and help the loser score without any resistance while lavishing him with high praise that he is just as good as his twin brother who is double and triple teamed to prevent him from ever enjoying any recreation. When he played football he hit the fence post with his helmet at full sprint on his first day of practice because he was too busy picking a fight with me to follow safety instructions to not hit the post head on at full sprint. He kept playing football and refused cataract surgery because he was obsessed with picking fights with me instead of working on his own short comings.
