If a=-13,b=5andc=-11 Verify that a+b=b+a
As we have a+b=b+a also, a=-13,b=5andc=-11
a+b=b+a
⇒-13+5=5+(-13)⇒-8=5-13⇒-8=-8
here LHS=RHS
Hence verified.
If A = {1, 2, 3}, B = {4} and C = {5}, then verify that :
(i) A×(B∪C)=(A×B)∪(A×C)
(ii) A×(B∩C)=(A×B)∩(A×C)
(iii) A×(B−C)=(A×B)−(A×C)
If a=-13,b=5andc=-11 verify that (a+b)+c=a+(b+c)
