.999... is not a number. It is a limit as the variable approaches
infinity [lim(n->infinity)(1-1/n)]. Infinity does not exist.
Therefore, .999... does not exist. It exists in theory because we treat
infinity as a number. That's fine, because it works. However, when we
treat infinity as a number in theoretical applications such as limits,
derivation, and integration, we have to remember that we are treating
infinity as a number, and can therefore manipulate it as a number with
operations such as subtraction and addition. That means we can take a
hypothetical number n=1-[1/(infinity-1)], which is equal to .999.... If
.999...=1, then 1-[1/(infinity-1)]=1, which means 1/(infinity-1)=0,
which means 1=0(infinity-1). This is clearly incorrect, since 0x, with x
being a number, is always equal to 0, and infinity is being treated as a
number in this situation. Of course infinity is not a number and cannot
be manipulated like this in real life, but infinity doesn't exist, so
using infinity in limits also doesn't work in real life. It only works
in theory when infinity is treated as a number. Claiming that .999...=1
is allowing infinity to be manipulated as a number in some ways that do
not work in real life but not in others, all within the same theoretical
situation. The difference between .999... and 1 is negligable to the
extent that they can be treated as the same number in practical
applications, but they are, by definition, not equal.

.9999...= 1 because 1/3=.3333... and 2/3=.6666... therefore 3/3=.9999... and 3/3=1

I don't math so I don't know but surely

1/3 does not really equal .33333 repeating because .99999 does not really equal 1, that is just the only way we have of demonstrating 1/3 as a decimal.

3/3 is obviously 1, not .99999.

Those are all approximations. 1/3=.333...+(1/3)*(10^-infinity)

this isn't correct

You're trying to look at infinity as a number, which it really isn't

op what does 999/1000 equal?

No. Infinity in terms of the real number you described is not the same as the ordinal infinity defined by the term 1/n, which is in fact a countable infinity - an ordinal number denoted ω of cardinality . The space between any 2 real numbers is an uncountable infinity, the first uncountable ordinal **ω1 **with cardinality** **.

And this is not treating infinity as a number. This is treating infinity as a two point compactification of the real line with maximal suprema and infima infinity and negative infinity.

of course it exists, because it is really just saying that whatever it is is as close as it can be to being it without actually being it.

that means that you go and go and go without actually getting to the desired goal/place/destination. in theory, that is infinity because it never ends.

so .999=infinity. it's completely theoretical, but it serves its important purpose to that end.

It's kind of like asking whether or not Vegans eat honey--it'll go and go and go through debate and argument, but, in the end, they'll be too indecisive to come to a final conclusion of yes or no. so it's always almost there, but will never get to finality.

This is why I'm in engineering. Theoretical math is frustrating. My understanding was that a fraction can equal a geometric series which can equal a repeating decimal (repeating term of any sort) which does make the repeating decimal an exact value. I really just do mass, flow and energy balances though so there's a 60-90% chance I'm talking out my ass.

the infinite sum of 1/n is the harmonic series - a divergent series represented by a non-repeating infinite decimal, but then, we're not looking at a power series here. We're looking an infinite sequence.

actually .999999... does in fact equal 1

if 0.999....=n then 9.999...=10n

therefore

10n-n=9.999...-0.999...

9n=9

n=1

0.999...=1
