It becomes undefined only when x=1.

How many nines can I write before the equation becomes undefined?

42?

In layman's terms: As you add more 9's to 0.999..., it approaches 1.  When you have "added" an infinite amount of 9's, the number literally is 1.  It's not close, it is 1.

f(x)=1/(1-x)

Within finite range. It will become undefined once 0.999... approaches infinity.

Quite the astute observation, and it's correct.

But, the OP explains otherwise. Which is what was being argued.

I still stand by my proof, and it has yet to be proven incorrect. All the strawmen, derailments, etc wont hide the fact that no one has been able to defeat my proof.

Haven't been on here in a while, but this discussion is driving me crazy.

Real numbers are abstract objects. 0.9999... is a particular way we REPRESENT one of these objects. We can represent the same object as 1.000... or for that matter just 1

I just realized this when I found that IV = 4, even though they look quite different...

... well, Dedekind cuts helped too.

It becomes 1 when you stop adding nines and add a 0.(some number of 0's)1.

Such as 0.99999 + 0.00001 = 1

You can't add enough nines to equal one, since adding produces a finite number of them.  0.999... is just another way of writing 1.

You definitely keep it simple.  But it's that simplicity that leaves me speechless with a face palm at times.  You're still right in the end, though, so who cares anymore.

No.  The number 0.999... with a finite number of nines approaches 1.  When the nines never end, 0.999... = 1

Nope. 0.(9) = 0.9999... = 9/9 = 1

Infinity = Aleph nought = the domain of countable numbers, and operates under an entirely different set of rules.

1 = 0.999...

0.999 ≠ ∞

It's 0.9 + 0.09 + 0.009 + 0.0009 + ...

Since the numbers grow increasingly smaller, they approach 1, not ∞.

0.999...9 ≠ 1 because it has a finite number of nines.

0.999... = 1.

This can be expressed in the proof I posted before, where it showed that 0.999...9 approaches 1.  When the nines stretch out forever (aka 0.999...), the number is 1.

You must put an infinite number of nines.  Same thing if you want 0.333... = 1/3.
