To be cear, by infinite i mean unlimited here. There is no false fraction, the truthfulness only comes from trying to evaluate it to a different number system.

A number [math]\frac{1}{3}[/math] is perfectly fine just being "one third". It doesn't need to be evaluated to a decimal to even perform arithmetic. We can all do [math]\frac{1}{3} × 3 = \frac{3}{3} = 1.0[/math], and this is a truthful evaluation since [math]\frac{n}{n} = 1[/math]. What is a false evaluation is [math]\frac{3}{3} = 0.\bar{9}[/math], because therre exists no mode or method dividing a sole 3 into another sole 3 which returns any amount of 9's.

You are dumb and didn't learn how to perform division and don't understand the concept of a remainder.


1 ÷ 4 = ???
1 - 4
1(0) - 4×[2] = 2 <----
2 - 4
2(0) - 4×[5] = 0 <----

1÷4 = 0.25

0 - 4
0(0) - 4
0(00) - 4
0(000) - 4

[math]\frac{1}{4} = 0.25\bar{0}[/math]
This value has terminating zeros. It is a unique result indicative of final precision.

1 ÷ 3 = ???
1 - 3
1(0) - 3×[3] = 1
1 - 3
1(0) - 3×[3] = 1
1 - 3
1(0) - 3×[3] = 1
...
1 ÷ 3 ≈ 0.333...
...
[math]\frac{1}{3} \approx 0.\bar{3}[/math]
The value lacks terminating zeros. It is not in final precision.

Now for something really funny, cause higher math is gay and retarded.
Lets switch this up a little and go back to pretending an infinite'th step in infinite work is achievable (it really isn't, but we'll pretend for the mathlets)
[math]\sum{n=1}^{\infty} \frac{3}{10^n}[/math]
You imply that at n=infinity, [math]\frac{3}{10^{\infty}}[/math] is equal to 0.
Well guess what, you just got your final precision didn't you. You know what else you got? A unique number. You multiply [math]0.\bar{3} × 3 = 0.\bar{9}[/math] and what you have is an infinite string of 9's with a final 0 at the end, which makes it a seperate and unique number that clearly isn't 1. Even if we simply rounded on the last possible digit, it's just a zero so it rounds down unchanging instead of rounding up to 1.

Since infinite sums are not how most people craft numbers or assume to perform division, we can just assume an infinite sum identity of 3/10^n is not really the same as 1/3. But dang, is it close!

Why am I surprised that a brainlet like you would be lost in the delicacies and intricate subtleties of my clever proof. Here's a proof that even a little brainlet like you might comprehend one day (it took me 5 minutes):

Allow us to define [math] \operatorname{f}(n)=\underbrace{0.999\cdots 9}_{n\text{ times}} [/math]. Using induction on [math] n [/math], proceed.
Basis of induction: most certainly [math] \operatorname{f}(0)=0<1 [/math].
Induction hypothesis: suppose thus: [math] \operatorname{f}(n)<1 [/math] for all [math] k\leq n [/math].
Induction step: henceforthwith [math] \operatorname{f}(n+1)=\operatorname{f}(n)+\underbrace{0.000\cdots 0}_{n\text{ times}}9 [/math]. Hark! [math] \operatorname{f}(n+1)<1+\underbrace{0.000\cdots 0}_{n\text{ times}}9 [/math].
However; [math] \underbrace{0.000\cdots 0}_{n\text{ times}}9\longrightarrow 0 [/math] and thence [math] \operatorname{f}(n+1)<1 [/math] as required. [math] \mathbf{Q.E.D.} [/math]

>> No.9734379

[math]0 \rightarrow \infty = \overbrace{\underbrace{0,1,2,3,4,\cdots}_{\infty \text{ elements of } \mathbb{R}}, \underbrace{\infty}_{\text{not in } \mathbb{R}}}^{\text{all possible elements}} \\ \text{Mapped between 0.9 and 1} \\ 0.9 \rightarrow 1 = \overbrace{\underbrace{0.9, 0.99, 0.999, 0.9999, \cdots}_{\infty \space \mathbb{R} \text{ elements of the map}}, \underbrace{1}_{\text{not in the }\mathbb{R}\text{ map}} }^{\text{all possible elements}} [/math]
If there exists a value to bridge the gap between 0.999... and 1 thus allowing 0.999... = 1, there also exists a value to bridge the gap between real numbers and infinity, thus allowing infinity to be equal to a real number.
If there exists no value to bridge the gap between 0.999... and 1 thus assuming 0.999... = 1, there also exists no value to bridge the gap between real numbers and infinity, thus assuming infinity to be equal to a real number.

Because the value does not actually exist and infinity cannot be reached, there is no possible value to add to 0.999... to make it reach 1; it will never reach 1. No amount of increments in the reals will reach infinity, so no mapped amount of increments between 0 and 1 will reach 1.

0.999... is not "infinitely close" to 1. It is actually infinitely far away from 1. Any arithmetic that shows 0.999... = 1 is therefore flawed by making inconsistent and mistaken assumptions about the construction of a repeating decimal extended from a poor interpretation and implementation of infinity, because infinity has classically always been poorly interpreted and implemented.

[math]0.\bar{9} \neq 1 [/math]

>> No.9734380

If there is not value in between 0.999... and 1, does that really mean that they are equal?
There is no integer between 3 and 4, but 3 doesn't equal 4.

I understand the 'proof'
x = 0.999...
10x = 9.999...
9x = 9.999... - 0.999... = 9
x = 1

Would this be more intuitive in another base?

Infinite 7's were removed from 0.777...
Infinite 9's were removed from 0.999...
The problem has not changed because each part of the equation was equally transformed.
0.2 + 0.7 = 0.9
0.2 + 0.7 < 1

0.222... + 0.777... = 0.999....
0.222... + 0.777... < 1

Now remember, the problem has not changed.

0.999... < 1

Some problems never change.
1/3 > 0.3
1/3 > 0.33
1/3 > 0.333

It doesn't matter how many extra 3's there are. If you can only ever append more 3's, there will always be a remainder, and if theres a remainder it's always unequal in flat decimal, and if it's always unequal then this evaluation only produces a result that is less than the fraction.

If you map each integer 0 to infinity to be real numbers between 0 and 1, there is no amount of incrementing in the map between 0 and 1 which will reach 1, so 1 is not in the real map.

Anyone can eyeball what 9/10th's of an apple looks like. Even though an apple isn't a number, it still has volume and size which means it can be measured and divided.

What is 9/10ths of infinity?
Doesn't exist. Infinity has no knowable size or length or volume.
What is 9/10ths of 1?
Well thats easy, its 0.9

So if you have the sum [math]\sum_{n=1}^{\infty} \frac{9}{10^n}[/math] this value approaches 1 but cannot reach 1, just like [math]\sum_{1}^{\infty} 1[/math] approaches infinity but can't reach infinity.

What your atrophied sac of shit brain fails to understand is that the limit is an analog for infinity. If your limit is 1, all possible values exist under 1, and none exist at or beyond 1. You've confused the analog for the literal real number 1 that naturally preceeds 2 and 3 and 4 and the rest of all real numbers.

But you didn't know that, did you?
Cause you don't think about the things you were taught. You just absorbed them like a janitor's mop soaking up the piss and shit you leave in the public bathroom. You absorbed them and regurgitated them when asked to provide answers on indoctrination tests. Here's your B+, you were a good goy swallowing all that garbage and puking it back up. Good little retard.

So again my dirty little beaner brained boy wonder, what is 9/10ths of infinity?

correct, but it can be made as close as you want to one, for any level of precision, i can give you a partial sum that is precise enough. This means that it never "reaches" one but can get arbitrarily close to 1. We call that number that it cannot reach but can be made arbitrarily close to the "limit". The infinite sum isn't saying we're adding up an infinite number of terms, it just asks "what's the limit?" which is 1. Do you understand why it's called a "limit" now?

>> No.9734985

>>9734973
The sum symbol doesn't say "add up terms until it reaches one" it says "what's that number that it can't reach but can be as close as we want to?" and that number is 1, as you said. The series is DEFINED to be that number it cannot quite reach, a series is not an infinite sum of terms, it's a convenient way to represent that limit.

>> No.9734986

What don't you get here fag?

You're confusing the analog of infinity, the limit of 1, with the real number 1. Its not the real number 1. Its an analog of infinity. You are not getting close to 1, you're only getting close to 0.999....

How close?

Lets take a sum of partials sums over 9/10^n up to an arbitrary point

0.9999...99 <---- n-1, previous
0.9999...999 <---- n, current
0.9999...9999 <---- n+1, next

So how close to 1 are you? It's certainly not within 1 element. So is it 2 elements?
10?
How close do you actually think you are to 1?

Are you confusing infinite arbitrary accuracy with knowable accuracy?
Like are you confusing that if 10 decimals are required, 0.999999999 is arbitrarily close to 1?
Do you not understand there is no implement of required decimal accuracy, and that the only limit of work is the balue to which n increments to, which is fucking infinity aka never ending?

You dont have to fill 10 decimals
You have to fill infinite decimals

Heres you:
0.9999999999

Heres the fucking requirement:
0.9999999999xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx...

Why do you think 0.999... is not representative of 0.9999...?

Not him but why do you think 0.999... is representing a final equivalence of absolutely infinite 9's of which there can be no greater amount of 9's, when you already know infinity as a final step is unachievable.

of course the obvious way of seeing 0.999... is just realizing there always exists another number greater than it by at least one more 9. Truly, there are an infinite amount of these numbers with more 9's that come between 0.999... and 1, and any attempt to imply invocation of the absolute final infinite'th value in this infinitely long set is reducing infinity to a finite real number and disregarding the intentionally incomprehensible nature of infinity by substituting an extremely truncated arbitrary value that truthfully is no less vague in execution than infinity itself already was: an otherwise entirely needless and facetious attempt at rationalizing infinity without actually making it any easier to understand, or a brainlet's trap of hubris.

Okay, I see where you're going with that. Approaching the situation that way would bring a person a back to where they started. Thank you for giving some insight.

This is math, not retard-ville. Prove that .999...=/= 1. Show a number that is strictly between the two.
