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
