Question

Match each equivalent expression with the property that it represents.

Associative Property of Multiplication
3 + (5 + 7) = (3 + 5) + 7
Identity Property of Multiplication
3 + 5 = 5 + 3
Identity Property of Addition
5(1) = 5
Commutative Property of Addition
(3 + 5) + 0 = (3+5)
Associative Property of Addition
[ 3(5) (4) = (3) 5(4)]

Answer 1

Explanation:

Answer 2

• Associative Property of Multiplication: [ 3(5) (4) = (3) 5(4)]
• Identity Property of Multiplication: 5(1) = 5
• Identity Property of Addition: (3 + 5) + 0 = (3+5)
• Commutative Property of Addition: 3 + 5 = 5 + 3
• Associative Property of Addition: 3 + (5 + 7) = (3 + 5) + 7

Explanation:

The associative property lets you move parentheses in a sum or product. That is, it doesn't matter which sum or product you compute first.

The commutative property lets you swap the order of operands in a sum or product.

The identity property says the operation using the identity element gives the original value, unchanged.
