1. Addition Properties Associative Property of Addition
Commutative Property of Addition
Identity Property of Addition

2. Associative Property of Addition
The property that states that the way in which addends are grouped does not change the sum
ex) (2 + 3) + 4 = 2 + (3 + 4)
(a + b) + c = a + (b + c)

3. Commutative Property of Addition
The property which states that the order of addends does not change the sum
ex) = 5 + 3
a + b = b + a

4. Identity Property of Addition
The property that states that the sum of any number and zero (0) is that number
ex) = 9
a + 0 = a
