Commutative property of mathematical addition of integers

The commutative property of mathematical addition of integers says that addition/summation of numbers in any order results into same answer. 
The commutative property of mathematical addition of integers can be represented as following

            a + b = b + a

To understand commutative property of mathematical addition of integers we can try adding numbers in different orders and note the results. 
For example,

If a = 5 and b = 3

Then 5 + 3 = 8 and 3 + 5 = 8

So, 5 + 3 = 3 + 5 as 8 = 8

           

Another example,

If a = 9 and b = (-5)

Then 9 + (-5) = 4 and (-5) + 9 = 4

So, 9 + (-5) = (-5) + 9 as 4 = 4
