Written a bit strange, and assuming that $\mathbb{Z}$ is indeed the general set the $x$ are taken from, it is correct.

It's ℤ, just like you said. Thank you so much for confirming!

I meant the arrangements, not the sets. One could have also divided by two directly in the first condition. And the snake for AND is certainly not standard.

Sorry. I misunderstood what you were objecting to. Now I see that you were referring to the calculations. I assumed that the "snake" is just meant to separate the two columns of calculations, not a mathematical symbol.
