Question

Verify that a + b = b + a

Answer 1

Let a=5 and b=9

then a+b= 5+9 = 14

and b+a =9+5 = 14

LHS = RHS

thus a + b = b + a

hence proved

Answer 2

Answer:For e.g,a=(-1) and b=(-6)//a+b=(-1)+(-6)=-1-6=-7 and b+a=(-6)+(-1)=-6-1=-7 .So,the answer is same even the number is positive or negative......Hence,a+b=b+a...
