I have to prove that $(A \cup B) \oplus A = A - B,$ where $\oplus$ is denoting the symmetric difference. I am trying to wrap my head around the problem and understand it but I am getting caught up on the fact that I can't properly visualize what $(A \cup B) \oplus A$ would look like. Any advice is appreciated.

Edit: It is possible that this is a false proof and I would have to provide sets showing so.
