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) + b

Or 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) =
