Order of Operations is used because when you have a problem with parenthases, exponents, multiplication ' divition, and addition ' subtraction then that is when you will need to put all of those into order and do each one step by step.
A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".
