Prove that 3.999... = 4
(In reply to

As 1/x goes on, it approaches 0. Does this mean 1/ some number equals 0? I think the key word there is approaches, not is. It can only exist in an infinite state, and we have already ruled that out. (In other words, this only works when you plug in infinity for x, and you can't do that.)
Your trying to use the converse of that postulatee. Sure 4 and 4 don't have any numbers in between them, but just because numbers don't have any space between them, doesn't mean that they are the same number; it's the other way around.
About dividing by 0 or infinity, you can't find a number that satisfies that. When I graph x/0, I think, what number times 0 equals the certain x I have chosen? I actually find no answer. So for x = any number, it won't appear. Maybe I am wrong by some super-math secrets or something, but the way I am thinking it is true.
I have no problem with being wrong, but I don't see a way to do it yet. :)
