To follow the order of operations in math, first do any calculations that are inside parentheses and take care of exponents and roots. Next, perform all multiplications and divisions, left to right. Then do all additions and subtractions, left to right.

A handy mnemonic for remembering the order of operations is PEMDAS, or "Please excuse my dear aunt Sally".
