Example 19 Let V = { a, e, i, o, u } and B = { a, i, k, u}. Find V – B and B – V Here, A - B = A - (A ∩ B) So, to find difference, first we find intersection V – B = V – (V ∩ B) V ∩ B = { a, e, i, o, u } ∩ { a, i, k, u} = {a, i, u} V – B = V – (V ∩ B) = { a, e, i, o, u } – { a, i, u} = {e, o} B – V = B – (B ∩ V) = B – (V ∩ B) = { a, i, k, u } – { a, i, u} = { k}
