4 What does order of operations mean?
Order of operations is the order in which you solve a math problem with many components. The first rule of order of operations is P.E.M.D.A.S. Don’t forget to solve the problem from left to right!

5 P l e a s E x c u s e M y D e a r A u n t S a l y

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

7 Exponents The second step of the order of operations is exponents.
á 52 = 25 Ex. 3 + (3 + 2)2 = 28 á = 28

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

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

10 Addition The fifth step of the order of operations is addition.
Ex = 9 Ex ÷ 2 = 4 á 3 + 2 = 4

11 Subtraction The last step of the order of operations is subtraction.
Ex. 16 – 4 = 12 Ex. 18 – (2 + 2)2 = 2 á = 2

12 Practice Copy the following problems into your notebook and practice them. (3 + 5) – 2 = 3 + 8 ÷ = 28 – 32 x 2 = (3 + 5)2 – 2 = Answers

13 Practice Copy the following problems into your notebook and practice them. 42 + (2 x 5) x 3 – 6 ÷ 2 = (3 x 2)2 ÷ 5 – = Answers

15 Quiz Copy the following problems on a piece of paper and hand them in when you are done. 12 x 2 – 4 x 6 = (12 + 2) – 12 ÷ 22 x 1 = Answer

16 Quiz Copy the following problems on a piece of paper and hand them in when you are done. (3 x 2)2 x 4 ÷ – 4 = (12 + 2) – 12 ÷ 22 x 1 = Answer
