I'm About to Blow Your Mind

[AWA1997]

You're supposed to do it from left to right, I don't know why you were taught that way. Your school system baffles me to every possible degree. Teaching that your blood would be toxic without periods (which is not taught in any other state or country as far as I'm aware) and other things, just... Why is your school the odd one?

Honestly, I was debating myself on where the three went in terms of parenthesis or multiplication.
