There is no such thing as negative numbers. "How do you take 5 apples from 3 when there are only 3 apples?" This was in elementary school in Wisconsin. The temperature regularly goes below zero. Pointing this out got me time in the corner. I'm still kinda salty about that.

    Maths unfortunately is hard to teach all at once, 1 year there's no negative numbers next year there is. Then they make it harder by adding letters. Get high enough, and you start doing stuff with infinite numbers, which I was also told can't be done.

    Science is the same way, but you can teach in a way that alludes to more complex subjects without denying those subjects. I actually called out my HS physics teacher when he kept having to correct grade school science lessons. He couldn't disagree with me that it's probably better not to teach incorrect lessons just because the correct lessons were more complex.
