Math Properties
Term | Definition | Example |
---|---|---|
Associative | Grouping can change | (a + b) + c = a + (b + c) (ab) c = a (bc) |
Additive Identity | Number/ variable + number = itself | a + 0 = a 7 + 0 = 7 |
Multiplicative Identity | Number/ variable x number = itself | b x 1 = b 9 x 1 = 9 |
Additive Inverse | Number/ variable + opposite of the Number/ variable = 0 | a + -a = 0 10 + -10 = 0 37 + -37 = 0 -17 + 17 = 0 ⅔ + -⅔ = 0 |
Multiplicative Inverse | Number/ variable x 1 over the number/ variable = 1 | b x 1/b = 1 2 x ½ = 1 3 x ⅓ = 1 27 x 1/27= 1 -5 x -⅕ = 1 ¾ x 4/3= 1 |
Multiplication Property of Zero | Number/ variable0 = 0 (Any number times zero = zero | a x 0 = 0 5 x 0 = 0 -5 x 0 = 0 ⅔ x 0 = 0 |
The Distributive Property | Multiply a sum by multiplying multiple numbers separately then adding the products together | a(b + c) = a(b) + a(c) |
Commutative | Order can change | a + b = b + a |
