Math Properties & Review

Front

Are these two expressions equivalent? 2 • (3 • 7) and (2 • 3) • 7

Back

Yes, because of the associative property

Front

Are these two expressions equivalent? 6 + 3 and 3 + 6

Back

Yes, because of the commutative property

Front

Example of the Commutative Property:
Options:
(4 + 8) + 7 = 4 + (8 + 7)
5 + 2 = 3 + 5
9 x 1 = 9
6 + 4 = 4 + 6

Back

6 + 4 = 4 + 6

Front

Example of the Associative Property of Addition:
Options:
1. 9 + 0 = 9
2. (3 + 8) + 5 = 3 + (8 + 5)
3. 4 + 3 = 3 + 4
4. 4 + (2 + 9) = (4 + 9) + 2

Back

(3 + 8) + 5 = 3 + (8 + 5)
