Webbx ∈ A, then x /∈ B (because otherwise x ∈ A ∩ B), so x ∈ A \ B. If x /∈ A, then by assumption x ∈ B, so x ∈ B\A. In either case, x ∈ (A\B)∪(B\A). This shows (A ∪ B) \ (A ∩ B) ⊆ x ∈ (A \ B) ∪ (B \ A). Together with the first part this shows the claimed set equality. 1.1.4 (d) Prove that (A∩B)×C = (A×C)∩(B ×C ...

WebbSuppose that ab = 0. Prove that either a = 0 or b = 0 (possibly both). Solution: Suppose that ab = 0. If a = 0 we’re done. The other possibility is that a 6= 0, and in this case we must show that this forces b = 0: Now a 6= 0 = )a 1 exists.
