Use the identity property of multiplication to fill in the missing number.
5 x _ = 5
1
True or false, when multiplying two numbers together the product will be different if you switch the order that they are in.
False
Use the associative property of multiplication to fill in the blank.
(1 x 5) x 7 = 1 x (_ x 7)
5
Use the inverse property of addition to fill in the blank.
_ + (-42) = 0
42
17 x 2 = 2 x 17
Commutative property of multiplication
Solve the problem then show how it is the identity property of multiplication.
55 x 1 = _
55 x 1 = 55
This is the identity property because if you multiply any number by 1, the number will always stay the same.
Use the commutative property of addition to fill in the blank.
47 + 92 = 92 + _
47
Use the associative property of addition to fill in the blank.
3 + (83 + _) = (3 + 83) + 6
6
True or false, if you add the opposite of a number the number will always equal zero.
True
5 + (85 + 16) = (85 + 16) + 5
Commutative property of addition
Use the identity property of addition to fill in the blank.
_ + 0 = 28
28
Use the commutative property of multiplication to fill in the blank.
38 x 72 = 72 x _
38
True or false, if you are multiplying the same three numbers together but switch the location of the parentheses the product of the three numbers will always be the same.
True
Use the inverse property of multiplication to fill in the blank.
37 x _ / 37 = 1
1
5 x (12 + 7) = 5(12) + 5(7)
Distributive property
Use the identity property of multiplication to fill in the blank.
(78 + _) x 1 = 78
0
Use the commutative property of addition to fill in the blank.
6 + 49 = _ + 6
49
Use the associative property of addition to fill in the blanks.
(3 + _) + _ = _ (8 + 10)
(3 + 8) + 10 = 3 + (8 +10)
Use the inverse property of addition to fill in the blank.
_ + (-17) = _
17 + (-17) = 0
(3 + 15) + 4 = 3 + (15 + 4)
Associative property of addition
True or false,
(17 + 19) x 1 = 37
False
Use the commutative property of multiplication to fill in the blanks.
180 x _ = 38 x _
180 x 38 = 38 x 180
Prove the associative property of multiplication to be true.
(25 x 5) x 2 = 25 x (5 x 2)
250 = 250
Use the inverse property of multiplication to fill in the blanks.
89 x _ / _ = 1
1 / 89
(6 + 16) + 0 = (6 + 16)
Additive identity
