Order Property of Addition

Order property of addition refers to two sets of addition in which numbers interchange or switch their places the answer remain the same.

Roger has 5 chocolates and then he got 2 more chocolates. Ben has 2 chocolates first and then he got 5 chocolates more.
Number of chocolates Roger has = 5 + 2
Number of chocolates Ben has = 2 + 5
From the above we can see that both have same number of chocolate which is 7.
That means if the numbers are same and if you add any number first answer remains the same.
For addition you can change the places of numbers.
For example : 5 + 2 is same as 2 + 5.

Example 1 :-

霴 霴 + 霴 = 霴 霴 霴
[ 2 + 1 = 3 ]

霴 + 霴 霴 = 霴 霴 霴
Example 2:-

6 + 8 = 14
8 + 6 = 14
Example 2:-
Sally goes to a bakery and buys 6 cupcakes. The baker tells her that 2 cupcakes are free.
6 + 2 = 8
2 + 6 = 8
