Determine whether the two expressions are equivalent. If so, tell what property is applied.

16+ 0 and 16

• No, the two expressions are not equivalent. The property applied is the commutative property.
• Yes, the two expressions are not equivalent. The property applied is the multiplicative identity property.
• No, the two expressions are equivalent. The property applied is the associative property.
• Yes, the two expressions are equivalent. The property applied is the additive identity property.

Determine whether the two expressions are equivalent. If so, tell what property is applied.

32+ 4 and 4 + 32

• Yes, the two expressions are equivalent. The property applied is commutative property of addition.
• No, the two expressions are not equivalent.

• Yes, the two expressions are not equivalent. The property applied is identity property of addition.
