ORDER OF OPERATIONS When a math problem has more than one operation, you must follow the RULES for the order of operations. Operations = multiplication, division, addition, and subtraction. Rules of Order of Operations: 1st: Compute all operations inside of parentheses. 2nd: Compute all work with exponents. (number Exponent ) 3rd: Compute all multiplication and division from left right. 4th: Compute all addition and subtraction from left right. THINK: P E M D A S (P = parentheses, E = exponents, M = multiplication & D = division, A = addition & S = subtraction) Note: If a rule does not apply to the problem you are solving, move to the next step. For example, if your math problem does not include parentheses, move onto 2nd step. If your math problem does not include exponents either, then move onto 3rd step. © Copyright NewPath Learning.

Example: 102 + (3 x 8) – 14 ÷ 2 1st: Parentheses 102 + (3 x 8) – 14 ÷ 2 102 + 24 – 14 ÷ 2 2nd: Exponents 102 + 24 – 14 ÷ 2 100 + 24 – 14 ÷ 2 3rd: Multiplication and Division 100 + 24 – 14 ÷ 2 100 + 24 – 7 4th: Addition and Subtraction Addition 100 + 24 – 7 124 - 7 Subtraction 124 – 7 = 117 102 + (3 x 8) – 14 ÷ 2 = 117 © Copyright NewPath Learning.
