I'm trying to prove the following by contradiction: [(A^B)-(B^C)]-(A^C)'=0. A, B, C are sets. All I know is in order to prove by contradiction you simply set the above not equal to zero. But I don't know where to go from there.(adsbygoogle = window.adsbygoogle || []).push({});

"^" means the intersection symbol.
