So I have.. x∈RHS <---> x∈(A-B)U(A-C) <----> x∈ A ^ xnot∈ B U x∈ A ^ xnot∈ C <---->x∈ A∩B' U A∩C' <----> x∈ A - (B' ∩ C') <----> x∈ A - (B ∩ C) ? man I am lost

Show that A - (B intersection C) = (A - B) union (A - C) I went about this completely around on a test but here is what I have Right Hand Side = ( A - B) union ( A - C) = (A intersection B) union (A intersection C) = A - (B intersection C) ? Easy problem but confused..thanks
