3 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21

4 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p)

5 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p)

6 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) +

7 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) +

8 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8)

9 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8)

10 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21

11 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p

12 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56

13 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21

14 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21

15 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21

16 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56

17 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56

18 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56

19 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56

20 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77

21 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77 -7p = 77

22 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77 -7p = 77 -7 -7

23 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77 -7p = 77 -7 -7

24 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77 -7p = 77 -7 -7 p = -11

25 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77 -7p = 77 -7 -7 p = -11 Ex. 2 -4(p - 5) = 12

26 Note: REVERSE Order of Operations! Ex. 1 -7(p + 8) = 21 -7(p) + -7(8) = 21 -7p - 56 = 21 + 56 +56 -7p + 0 = 77 -7p = 77 -7 -7 p = -11 Ex. 2 -4(p - 5) = 12 -4(p) – -4(5) = 12 -4p + 20 = 12 - 20 -20 -4p + 0 = -8 -4p = -8 -4 -4 p = 2
