For example: I don’t believe in the axiom of choice nor in the continuum hypothesis.
Not stuff like “math is useless” or “people hate math because it’s not well taught”, those are opinions about math.
I’ll start: exponentiation should be left-associative, which means a^b should mean b×b×…×b } a times.
It’s been a few years since my math lectures at university and I don’t remember these two being explained so simple and straightforward (probably because I wasn’t used to the syntax in math at the time) so thanks for that! This’ll definitely stick in my brain for now
