# Number properties

### Associative, Commutative, Inverse, Identity, Distributive

Commutative Property Change Order: a + b = b + a c*d = d*c 4 + 6 = 6 +4
Associative Property Always same: Think moving cheeks. (a+b)+c = (a+b)+c (7+3)+5 = 7+ (3+5) (c*d)*e = c*(d*e)
Inverse Property Opposite! (a) + (-a) = 0 1/a * a/1 = 1 8+-8= 0 1/9 * 9/1 = 1
Distributive Property Distribute a number through a parenthesis. - Watch for negatives! The sign always goes with the number behind it!a(b+c) = ab + ac 3(a+6) = 3a + 18
Identity Property No one can change you! a + 0 = a a*1 = a 4 + 0 = 4 31 * 1 = 31
