Properties of Addition

1. Zero or Identity Property

When zero (0) is added to a number, the number remains thesame.

5+0 = 0

2. Commutative or Order Property of Addition

Changing the position or order of the addends does not changethe sum.

2 + 3= 53 + 2 = 5

3. Associative or Grouping Property of Addition

Changing the grouping of the addends does not change the sum.

(2 + 6) + 4 = 2 + (6+4)

8 + 4 = 2 + 10

12 = 12

--parts:

Shoulders• chest—formed by ribs

heart and lungs protect the lungs and heart
