Commutative Property of Addition      

Definition:

It doesn’t matter which order the numbers are added, any case we will get same answer.

Example 1: If we adding three and four together we get, 

                             3 + 4 = 7

              Let’s look that when we add 

                             4 + 3 = 7

    We get same answer, that is 7.

               So,          3 + 4 = 4 + 3 
               or           3 + 4 = 4 + 3 = 7 

We get same answer when we change the adding order. 

Example 2: If we adding two and three together we get 
                             2 + 3 = 5

              Let’s look that when we add 

                             3 + 2 = 5

    We get same answer, that is 5.

               So,          2 + 3 = 3 + 2 
               or           3 + 2 = 2 + 3 = 5 

We get same answer when we change the adding order.

Example 3: If we adding five and six together we get 
                             5 + 6 = 11

Let’s look that when we add 

                             6 + 5 = 11

                   We get same answer

It says that the numbers can be added in any order, we will get same answer.

So, the commutative property of addition says that when we add numbers will get same answer whether we switch the order.

Formula-            a + b = b + a

This rule also apply for more than two numbers.
We add two three and four together 

       2 + 3 + 4 = 9

or    3 + 2 + 4 = 9

or    4 + 3 + 2 = 9

We see that, we change the order of numbers but get same answers.
