FHSLanguage of Mathematics2 What is the Order of Operations? We can use the following expression to remember the order of operations (which operation do we do in which order?) Please excuse my dear Aunt Sally Do what is inside parenthesis first Do the exponential expressions next Do the multiplication or division in order from left to right Do the addition or subtraction in order from left to right

FHSLanguage of Mathematics3 Examples Here are some examples of problems that require simplification: (5 4) ÷ (7 – 5) + 3 2 – 1 8 = 2 11 + 18 ÷ 3 2 – 7 = 3(4 + 5) – 3(8 – 2) – (5 – 2) = (3 5 + 5 7) ÷ (10 ÷ 2) 2 = 18 17 6 2
