comment Proving : $A \cap (B-C) = (A \cap B) - (A \cap C)$
Hi @Marnix! It was a bit odd to read your comment years after posting, but then I think you've a point. But as I said in my answer, I tried to simplify :) the notation of your answer, using sets. As I see, your answer also has a trick point in which the reader has to understand how a left value is carried to the expression inside brackets. I think both answers are good.
