If a = 79 and b = 191, Prove a + b = b + a.
And also write what this property is known as ? 
Given a = 79, b = 191
Now, we have to prove:
a + b = b + a
Put the values of a and b from above and we get:
79 + 191 = 191 + 79
270 = 270
L.H.S. = R.H.S.
Hence proved a + b = b + a.
This property is known as Commutative Property for Addition of Whole Numbers.
