What is an order of operation?
The way to memorize the order of operation is by remembering this sentence: Please Excuse My Dear Aunt Sally...P for parentheses..E for exponents M for Multiplication..D for Division..A for Addition..And S for Subtraction. When you get a math problem like this: 15 + (10 x 4) you do what's in parentheses first. So 10 x 4 is 40. Then you would go 40 + 15 and the answer is 50. Then you have completely mastered that math problem. But remember you have to do the order of operation in order to figure out the math problem. Bye! Hope I helped! have any questions? just ask!
