Show thata⊕b = (a ∪b) – (A ∩b).

In this question we have to show A⊕B = (A∪B) – (A∩B).

Step 1 </p>

A⊕B means symmetric difference of A and B.

It means that an element is in (A∪B) – (A∩B) means that the element is in (A∪B) but not in (A∩B) that is it is not in both A and B but it is in either A or B.
