I can't believe this is even a real debate.

Anyone who clicked no clearly needs to stay in school for a long time.

To people who say "draw a line 0.999... long" or "write 0.999... and keep adding 9s" and then conclude that it cannot equal one no matter how "close" you get:

You are incorrectly making the assumption that 0.999... is a finite number. That's the mistake so many people make, even if unconsciously. 0.999... is equal to one. There are several proofs of it and whether you like it or not, that's how it is.

Yes, it's 1, and no, there isn't really a debate over this. The confusion is due to the fact that most people don't understand infinites very well. Infinite is not a number (you can't add or substract anything from it, because it'll always be infinite), so while 0.999(repeating) LOOKS like a number, it's not, but it's value is the same as the number 1.

It doesn't feel right to most because when you see 0.9999...., you naturally think it's 0.9999 rather then 0.(infinite amount of 9's).

It's more or less the same way 1/4 is 0.25, they don't look the same, but they have the same value nonetheless.

interesting

so many people say that 1/3 = .333333333333333333....
prove it, otherwise your entire argument falls apart
