PEMDAS
Mathematical order of operations.
Parenthesis, exponent, multiply, divide, add, subtract.
I only learnt this a year ago and it's almost embarrassing how much my maths or ability to understand math has improved from this(I'm 28 and never gotten taught this in schools general maths so I used to find math really difficult).

I'm curious, where did you go to school. I remember learning PEMDAS in 6th grade (New York State) and it's been burnt into my brain since.
