Just remember this phrase, please excuse my dear aunt sally, it will always be in this order, take the first letter of each word, the p in please stands for parentheses, the e in excuse stands for exponents, the m in my stands for multiplication, the d in dear stands for divide, the a in aunt stands for addition, & the s in sally stands for subtraction, so just to be clear first step is to do whats in the parentheses, 2nd step is to do the exponents, 3rd step is to multiply, 4th step is to divide, 5th step you add, and the last step you subtract, in that order.
