Question | Answer |
Commutative Property of Addition | a + b + c = b + a + c |
Commutative Property of Multiplication | abc = bac |
Associative Property of Addition | (a + b) + c = a + (b + c) |
Associative Property of Multiplication | (ab)c = a(bc) |
Distributive Property | 4(x + 2) = 4x + 8 and (3 – x)2 = 6 – 2x |
Substitution Property | if x = 10 then 5x = 50 |
Identity Property of Addition | 5 + 0 = 5 |
Identity Property of Multiplication | 7(1) = 7 |
Inverse Property of Addition | 6 + (-6) = 0 |
Inverse Property of Multiplication | 3(1/3) = 1 |
Symmetric Property | if a = b then b = a |
Addition and Multiplication Property of Equality | if a = b then a + 5 = b + 5 |
Addition and Multiplication Property of Inequality | if a < b then 3a < 3b |
Zero Product Property | If ab = 0 then a = 0 or b = 0 and (x-5)(x+2)=0 then x = 5 or x = -2 |
