I found out today there are people that know PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtractions
But don't realize the M before the D doesn't mean you multiply first then divide, but that Multiplication and Division are the same step and you do them in order, regardless of which one it is, from left to right.
Multiplication and Division are essentially the same thing and you can rewrite a multiplication problem as a division problem and vice versa.
Same for Addition and Subtraction.
