4. Parentheses The first step of the order of operations is parentheses. Ex. (3 x 6) = 18 Ex. (3 x 6) + 2 = 20  18 + 2 = 20

5. Exponents The second step of the order of operations is exponents. Ex. (3 + 2) 2 = 25  5 2 = 25 Ex. 3 + (3 + 2) 2 = 28  3 + 25 = 28

6. Multiplication The third step of the order of operations is multiplication. Ex. 6 x 4 = 24 Ex. (3-2) x 4 = 4  1 x 4 = 4

7. Division The fourth step of the order of operations is division. Ex. 8 ÷ 2 = 4 Ex. 8 ÷ 2 + (3 x 6) = 22  4 + 18 = 22

8. Addition The fifth step of the order of operations is addition. Ex. 3 + 6 = 9 Ex. 2 + 4 ÷ 2 = 4  2 + 2 = 4

9. Subtraction The last step of the order of operations is subtraction. Ex. 16 – 4 = 12 Ex. 18 – (2 + 2) 2 = 2    18 - 16 = 2
