comment Show that $(A ∩ B) ▵ C = (A ▵ C) ▵ (A \setminus B)$
Hi Daniel. It is from the book "How to prove it". The question said that I could prove the equality by any method, Venn diagrams was a bit easy so I thought about using logical connectives instead.

Thank you for your comment @TerraHyde , if you have time I would love to see how you would do the development using set operations.

comment Understanding implication in logic truth tables (excerpt from textbook)
Thanks for your answer! This is not how I understand the question. To me they are saying that if we make $P \implies Q$ false, the we don't need to look at $P$ and we can see that $Q$ is true by looking at line $2$ and $4$... I don't understand the logic in this...
