WebMore complex proofs require nested sequences of Modus Ponenses. Theorem 4. Let Aand Bbe two sets. If A[B= A\Bthen A B. Proof. Assume that A[B= A\B. We shall prove that x2A =) x 2B, which by de nition is equivalent to the consequence of the theorem. Assume that x2A. Since A A[B, then x2A[B. We assumed that A[B= A\B, so x2A\B.
