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.
