Consider the following statement. For all sets A and B, ((A° U B°) -A) = A. An alternative proof is shown in Appendix B. Proof: Suppose A and B are any sets. Then, ((AC U Bº) - A) C = ((Ac U Bc) n Ac)c = (Acn (Aº U Bc)) = = = || || by the set difference law by the commutative law for n ((Aºn Aº) U (Aºn B)) by the distributive law (AC U (Aºn B°)) ---Select--- (AC)C ---Select--- ---Select--- = A X X
