Evaluate 43
64
Write 29 as repeated multiplication and solve.
2x2x2x2x2x2x2x2x2= 512
Find the Values and Solve the Problem: 54 __ 83
625 > 512
Find the Values and Solve the Problem: 64 __ 46 __ 84
1,296 < 4,906 > 4,096
22 ÷ 2 + 20 - 5 =
26
5 x 3 + 8 x 2 =
31
8 ÷ (1 + 3) x 52 – 2 =
48
(50 x 4 – 80) ÷ 4 x 16 + (2 x 6) =
42
(53 – 52+ 50) x (34 ÷ 9) =

Use Mental Math to solve: 5 + 25 + 12 =
42
Show the Associative Property and solve (Show your work): 23 + 46 + 7 + 14 =
(23+7) + (46+14) = 90
Show an example of what the Commutative Property means by using letters a, b, and c.
(a + b) + c = (a + c) + b Or a different combination that represents the same answer.
Using the Distribution Property (Show your work), what is: 5 x 57 =
5 x (50 + 7) = (250) + (35) = 285
Solve using the Distributive Property and show your work: 4 x 66 x 2 =
8 x (60 + 6) = (480) + (48) = 528
Find the answer and state which method of computation you used: 16 + 2 + 4 + 13 + 5 + 1 + 14 =
