Order of Operations Note: Write the initials for “Pretty easy rememberin g my dear Aunt Sally” and PERMDAS down the page! PP E,R M,D A,S Once written, follow the order step by step.
Order of Operations First Do: Example: You try: Pretty = parenthesis 15 - (4+7) = 12 + (9-5) =
Order of Operations Second Do: Example: You try:
Order of Operations Third Do: Example: You try: My = Multiply OR Dear = divide Note: If both operations, multiplication and division, are in the same equation, go in left to right order and take the operation that comes first. 48 (4 x 2) x 3 = x 2 =
Order of Operations Fourth Do: Example: You try: Aunt = add OR Sally = subtract Note: If both operations, add and subtract, are in the same equation, go in left to right order and take the operation that comes first. (4+7) + 6 = 12 - (9-5) + 7 =
Order of Operations You try: x 2 = 7 – (4 + 3) x 3 = (4+7) + 6 x 2 = 2 x (9-5) + 7 – 3 =
