I assume you're referring to the way numbers are calculated in mathematical equations. The way to remember it is BODMAS. That is an acronym for Brackets, Order, Division, Multiplication, Addition, Subtraction.
Say you had the (relatively) simple sum of 3 / 2 + 3 x 4...
Reading from left to right, you get the answer 18 - however - using BODMAS, you get 13.5
Subtraction, division, cross multiplication of vectors, multiplication of matrices, etc.
