This isn't "sloppy language", it's just wrong. Don't try to downplay spreading misinformation. It remains true that there are infinitely many rationals in (0, N) and (N, 1), and yet it is entirely possible to enumerate the rationals (i.e. assign indices).
> There's an infinite number of those between 0 and 1 as well, but because it's a subset, there are "fewer" of them.
Also misinformation. (0, 0.5) is a subset of (0, 1) yet the two sets have the same cardinality, whether we take them both in Q or both in R.

I made the "sloppy language" edit before I fully understood them. > Don't try to downplay spreading misinformation. > Also misinformation. LMAO. Every incorrect thing you see on the internet isn't the work of a Russian troll or whatever you're trying to accuse me of here. Sometimes people are just mistaken. Your comment actually has some interesting points that could add to the discussion, but it's ruined by the impotent nerd rage.
