Answer 2

COMMUTATIVE PROPERTY---It does not matter which number is first when you write the problem.
examples...5+3=3+5, 9+7=7+9 or a+b = b+a or ab = ba
ASSOCIATIVE PROPERTY---Involves 3 or more numbers, two numbers are in parenthesis(they are "associated" together).
examples...(2+5) +4=11, 2+(5+4) = 11...remember,always do parenthesis first, order of operations. a+(b+c)=(a+b)+c or a(bc) = (ab)c
DISTRIBUTIVE PROPERTY---The sum of two numbers is equal to the sum of each addend times a third number.
examples..4 x (.6+3)= 4 x 6 + 4 x 3, 5x (1+2)= 5 x 1+ 5 x 2, a(b+c) = ab +ac or (b+c)a=ba + ca.
IDENTITY PROPERTIES---
1. addition--additive identity is 0. a+0=0+a = a
2. multiplication--multiplication identity is 1. a(1)=1(a)=a
INVERSE PROPERTIES--
1.additive inverse(or negative)...a + (-a) = 0
2. multiplication inverse (or reciprocal)...a (1/a)= (1/a)a = 1
