Can someone help me prove that
$$X \times (Y \times Z) \sim (X \times Y) \times Z$$
I know that there is supposed to be a bijection between these two. The first one will contain elements like $(x, (y, z))$ and the second one $((x, y) z)$. I just need some instructions, I believe I can manage on my own from that.
