Properties of Real Numbers

• Multiplicative Inverse

• Multiplicative Identity

• Commutative

• Associative

Identify the example that represents the

Multiplicative Property of Zero.

• -9 x 0 = 0

• -9 + 9 = 0

• 9 - 9 = 0

• 9 + 0 = 9

What property is this?
1a = a

• Commutative Property of Multiplication

• Multiplicative Inverse

• Multiplicative Identity

• Distributive Property

• Additive Identity

• Additive Inverse

• Multiplicative Property of 0

• Multiplicative Inverse

If you multiply a number and its multiplicative inverse, what do you get?

• 0

• 1

• Not enough information

• None of these

Pick the answer that is an example of the commutative property of multiplication

• b + c + a = a + b + c

• a(b + c) = ab + ac

• a ⋅ b = b⋅ a

• a ⋅ 1 = a

Pick the answer that is an example of the identity property of addtion

• a + (-a) = 0

• 1 + 1 = 2

• a + 0 = a

• a + b = b + a

Identify the property

a(b + c) = ab + ac

• Associative property of addition

• Distributive property

• Commutative property of addition

• Inverse property

To solve this equation, which property would be useful:

• Additive inverse

Any number you multiply by zero is equal to zero.

• True

• False
