Question | Answer |
---|---|
ab=ba | Commutative Property of Multiplication |
3(x)=x(3) | Commutative Property of Multiplication |
x + −x = 0 | Inverse Property of Addition |
6(ab) = (6a)b | Associative Property of Multiplication |
1/y∙ y = 1 | Inverse Property of Multiplication |
2 + 5y = 5y + 2 | Commutative Property of Addition |
3(4 + 2) = 3(4) + 3(2) | Distributive Property |
1/5 ∙ 5 = 1 | Inverse Property of Multiplication |
p + 0 = p | Identity Property of Addition |
3x + 4 = 4 + 3x | Commutative Property of Addition |
c ∙ 1 = c | Identity Property of Multiplication |
(xy)z = x(yz) | Associative Property of Multiplication |
(3 + a)+ b = 3 +(a + b) | Associative Property of Addition |
