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.

As far as I’m concerned there are always letters. We just hide them or when they are young use a question mark.
2 + 5 = ?
Is super basic algebra if you just change the question mark to an X.
When you say “in the corner”, I’m guessing this was one of those really, really old small schools you’d see in Little House on the Prairie.
