When should you use PIMDAS in math?

Well, darling, you should use PEMDAS (not PIMDAS) when you want to solve mathematical expressions with multiple operations. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). So, next time you see a math problem, just remember PEMDAS and you'll be good to go!
