Thank you very much! The terminology really helps when researching this!

comment Why is proof of the [topological] closed graph theorem incorrect?
Thanks; I see now there's nothing guaranteeing that $N$ can be be written as $U' \times V'$ with $U'$ definitely a subset of $U$. Can I fix this approach or am I off altogether? I could use some hints going forward because I'm pretty stumped.

comment Which is larger? $20!$ or $2^{40}$?
Guys, I think the point is that anyone could have plugged these numbers into their calculator in a second. Posters who ask questions like these usually have the implicit assumption that they want to prove it elegantly without explicit computation - for novelty purposes.

comment How can I better understand manipulating “operators” in mathematical relations?
Thanks. Okay, I understand that you can do this algebra of functions, but if I just have some operator or map $A : U \rightarrow V$ and I have an element $u \in U$, then when I write $Au$ I mean the result of applying operator $A$ with input $u$? Is writing the operator next to a member of its input type "implied application"?
