  2. When asked to find the Value, you are actually asked to find thee _______.

  3. Answer

  4. 49The 4 is the _____ and the 9 is the ______.

  5. 4 is the base9 is the exponent

  6. What are the 3 key words when talking about the Distributive, Associative, and Commutative Properties?

  7. Distributive – DistributeAssociative – GroupingCommutative - Order

  8. What are the 4 steps to solving a problem we talked about at the beginning of the year?

  9. 1. Understand the Problem2. Make a Plan3. Solve4. Look Back

  10. P.E.M.D.A.S. is the acronym that we use when talking about this section of the book. (1-4)

  11. Order of Operations

  12. What is 9x9x9x9x9 in exponential form?

  13. 95

  14. Evaluate 43

  15. 64

  16. Write 29 as repeated multiplication and solve.

  17. 2x2x2x2x2x2x2x2x2=512

  18. Find the Values and Solve the Problem:54 __ 83

  19. 625 > 512

  20. Find the Values and Solve the Problem:64 __ 46 __ 84

  21. 1,296 < 4,906 > 4,096

  22. 22 ÷ 2 + 20 - 5 =

  23. 26

  24. 5 x 3 + 8 x 2 =

  25. 31

  26. 8 ÷ (1 + 3) x 52 – 2 =

  27. 48

  28. (50 x 4 – 80) ÷ 4 x 16 + (2 x 6) =

  29. 42

  30. (53 – 52+ 50) x (34 ÷ 9) =

  31. 1,350

  32. Use Mental Math to solve: 5 + 25 + 12 =

  33. 42

  34. Show the Associative Property and solve (Show your work): 23 + 46 + 7 + 14 =

  35. (23+7) + (46+14) = 90

  36. Show an example of what the Commutative Property means by using letters a, b, and c.

  37. (a + b) + c = (a + c) + bOr a different combination that represents the same answer.

  38. Using the Distribution Property (Show your work), what is:5 x 57 =

  39. 5 x (50 + 7) =(250) + (35) =285

  40. Solve using the Distributive Property and show your work:4 x 66 x 2 =

  41. 8 x (60 + 6) =(480) + (48) =528

  42. Find the answer and state which method of computation you used: 16 + 2 + 4 + 13 + 5 + 1 + 14 =

  43. Paper and Pencil or Mental Math Answer : 55
