comment ZFC Union axiom
So to me it's hard to read it straight from left to right. As I read it now, its "the set Y is the set for which any element z is an element of y if and only if there's some set w such that w is in x and z is in w"

Sorry, I was asking for clarification on the sentence. I think you were missing a word there. We are then WHAT y?

comment ZFC Union axiom
Thanks Andre. I'm almost there. You're saying that we're describing a set that contains other sets and showing that y includes the contents of all these sets. Is that correct? Also, the ∀z means what exactly?

"inner formula" refers to ∃y∀z? Could you explain how that's read?

Gotcha. Thanks Austin. Thinking about it like a promise is certainly helpful.
