The properties of addition are really easy once you understand them very well. So what are the properties of addition? The properties of addition say that:

1) If two whole numbers are to be added then the sum is to be whole number as well, example:-

3+3=6

9+2=2

0+0=0

2) The sum of two whole numbers will always remain unchanged so the numbers can interchange places, example:-

6+2=8

__2+6=8__
0+4=4

__4+0=4__
4+2=6

__2+4=6__
3+0=3

__0+3=3__3) The sum of three whole numbers will always remain the same if the order in which they are grouped is changed, example:-

7+(4+5) OR 4+(7+5)

(7+5)+4 OR 5+(5+4)

4) If zero is to be added to a number then the sum is the number itself, example:-

7+0=7

0+5=5

Now try some of these and make sure to watch the video on YouTube.
