comment Math Symbols for “Must be Finite”
Interesting so although N's cardinality is countably infinite because there is no finite number to accurately describe it, we use n ∈ N to describe a finite number.

Yes maybe.. But at least "must be finite" should be expressable in math shortags if I may call them so, no?

comment Is a subset an element of a set?
Why the downvotes? What did I say wrong. In fact this is a trivial question, but yet it is something I saw as a legit question in an actual exam, baffled by its simplicity, I wanted to make sure that I am not the only one. So don't shoot the messenger.

Thanks for your answers. @MattAllegro why don't you post a reply where you elaborate on the bijective image idea. I would give you the answer then.

comment Is the set of real numbers not a subset of the set of whole numbers?
I understand the difference, but when you say "shouldn't be used", do you mean it could cause ambiguous interpretation?
