SOL 4. 22 Algebra Commutative & Associative Properties By, Mrs. Sagendorf

Commutative Property of Addition n Definition – The addends can exchange places and still equal the same sum. n Example – 7+2=2+7

Commutative Property of Multiplication n n Definition – The factors can exchange places and still equal the same product. Example – 3 x 2 = 2 x 3

Associative Property of Addition n n Definition – The addends can be grouped differently and still equal the same sum. Example – 2+(3+4)=(2+3)+4

Associative Property of Multiplication Definition – The factors can be grouped differently and still equal the same product. n n Example – 5 x(3 x 2)=(5 x 3)x 2
