We know that addition is commutative for whole numbers, does it apply same as on integers ? 
Explain commutative property for addition of integers, with variables x and y. 
Prove Addition is commutative for integers with the help of two negative integers i.e. (86) & (14). 
Prove Addition is commutative for integers with the help of two positive integers i.e. 67 & 49. 
Prove Addition is commutative for integers with the help of one positive integers & one negative integer i.e. 113 & (247) 
A) If a = 58 and b = 72, prove a + b = b + a and also write what this property is known as ?
B) If x = (127) and y = 282, prove x + y = y + x and also write what this property is known as ?
C) If p = (369) and q = (842), Prove p + q = q + p and also write what this property is known as ?
