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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  24. 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 Note: REVERSE Order of Operations!

  25. 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 Note: REVERSE Order of Operations!

  26. 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 Note: REVERSE Order of Operations!
