Cite a property from Theorem
Deriving a Set Difference Property
Construct an algebraic proof that for all sets A, B, and C,
(A ∪ B) – C = (A – C) ∪ (B – C).
Cite a property from Theorem 6.2.2 for every step of the proof.
Solution Let A, B, and C be any sets. Then
Exercise
For all sets A and B, A – (A ∩ B) = A – B.
