Is there anywhere to look for proofs that deal in tackling the set theoretic operations - what can and what can't be expressed through another operation?(adsbygoogle = window.adsbygoogle || []).push({});

For example: prove that the difference of 2 (or N) sets cannot be expressed through the intersection operator.

Given A,B we cannot

I'm not exactly sure how to express myself in English in this topic, I hope it's concise enough.

Thanks
