0.999... = 1

Unfortunately your video doesnt match your argument. The video uses my first proof at time stamp 1:50, and my second proof at 6:10. So not only does it support my conclusion, but also my methods.

Here's a video to explain it. .9999... is a number, not a real one. It explains basic calculus as well, as that's the method used to prove this.
https://www.khanacademy.org/math/math-for-fun-and-glory/vi-hart/infinity/v/9-999-reasons-that-999-1

It explains that it is true, but requires more in depth math to truly understand and apply. What you said is true, but the methods aren't true.

I didnt forget that factor. I didnt say its infintely close to 1. I said it IS one.

Its also very much a real number, an official category with an official definition. Not only is 0.999... a real number, its a "rational" number, unlike pi, or square root of 2 which are "irrational numbers"

Infinity is not a number, but 9.999... is not infinity. It has infinite 9s after the decimal point, but it isnt itaelf infinity. How can a number smaller then 11 be infinity?

The math i used was math intended to be used for repeating decimals. Did you really read my arguments? Or are you offering to be a new challenger?

You forgot a key factor. A number infinitely close to 1 but isn't 1 is technically outside the real numbers category, therefore you can't convert it as could be done with normal mathematics. Yes, irrational numbers can be done so, but they are considered Real Numbers as well. .99999999999, forever, is NOT considered a, "real number." And therefore can not be simplified to one.

Infinity (which is the case with 9.99.....) is not considered a real number, as you can't add or subtract 1 from infinity. It's still infinity, regardless. There's no end to 9.99...... as the 9's can continue on forever. So, using math for real number's don't apply.

I wish that were always true, especially in online debate channels :p Perhaps if i knew the person better.

Oromagi,
Thanks for clarifying.

Nemiroff,
You can probably still pull the point off just fine.

A good benchmark I look at, is if the words seem too absurd to be believed by the person stating them. As a hilarious example, the majority of this debate: https://www.debateart.com/debates/866/fetuses-as-a-replacement-for-the-usd

Well that settles that lol.
This does negate one of my arguments in another debate so thats vexing. Lol

My statement that he was engaging in sarcasm is an assumption, but one grounded in him not seeming to be insane elsewhere on this site. So I firmly believe he was saying "lazy" in jest, not expecting anyone to ever fill the entire universe with repeating decimal points. Were someone to hypothetically do so, there would be no room left for the existence of 1.00000...., all that would be left is 0.99999....

Just to confirm I was not genuinely criticizing PRO for failing to represent infinity in actual space-time, since that would break the universe I’m using presently. In truth, I am mostly pro-abstraction.

No, i do not.

Sarcasm is incredibly hard to convey through text, especially with no attempt to clearly convey it, and to someone who knows nothing about you. Furthermore his second paragraph explaining why he voted for pro with "nevertheless", a statement that supports the assertion that he is voting against his beliefs.

May i recommend either of: 😜,😋,🙃,👹,💩 or 😇 to denote sarcasm. Those who are not emoji-able can use the less technical :p

To be honest it seemed like yet another misunderstand of infinity. Not that ridiculous when 2 debators had already just made that mistake.

Saw you reference a vote here in a debate, and just to be clear, you know that was sarcasm right?

>>If PRO wasn't so lazy and instead took the time the fill the known universe with repeating nines it would be apparent to everybody that the integer 1 is quite different from the infinitely inexpressible .9999....
>Oromagi insisted that my claim was incorrect and that he could have done a better job (i disagree as my claim is a clear cut fact), but still voted for me based on the merit of my arguments.

I can take your challenge if you like :D

Criterion Pro Tie Con Points
Better arguments ✔ ✗ ✗ 3 points
Better sources ✗ ✔ ✗ 2 points
Better spelling and grammar ✔ ✗ ✗ 1 point
Better conduct ✔ ✗ ✗ 1 point
Reason: I for one am totally unimpressed with this popular assertion- the only reason the math works is because PRO shorthands the infinitely repeating decimal point. If PRO wasn't so lazy and instead took the time the fill the known universe with repeating nines it would be apparent to everybody that the integer 1 is quite different from the infinitely inexpressible .9999....

Nevertheless, PRO did the math and backed his argument with citations. CON offered one assertion without any proofs and that was easily falsified in certain creative contexts. PRO made his case.

Grammar to PRO for CON's misuse of the adverb "literally" which means 'verbatim'- no metaphor should be here read. This VOTER scoured the debate for some reference to the division of follicles and finding none, failed to comprehend CON's intention or cohere this statement to implied thesis.

Conduct to PRO for CON's single forfeit

I've re-voted, with an expansion on S&G.

As per the original vote... Since you think the quoted bit under S&G ("you are splitting hairs , literally!") was neither incoherent nor incomprehensible, would you please explain its connection to the concepts under discussion in this debate? To me it is self evidently not. Bare in mind, this is the entirety of a round I've copy/pasted.

Reason for Mod Action>Reason for Mod Action: This RFD is fine except for the spelling and grammar point.

In order to award spelling and grammar (S&G) points, a voter must explicitly, and in the text of their RFD, perform the following tasks:

Give specific examples of S&G errors
Explain how these errors were excessive
Compare each debater's S&G from the debate

S&G errors are considered excessive when they render arguments incoherent or incomprehensible.

Although the voter did compare the grammar with the other side, ragnar did not explain why it was excessive and rendered the arguments incoherent or incomprehensible. It's not enough to vote for grammar for one or two minor spelling mistakes.

For this, let X=0.9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999...
Arguments:
Pro showed with examples of mathematical proof that X is verifiably not less than 1. Con counters that 1 is greater than anything less than 1, but failed to in any way even try to connect this to X (if X is less than 1 by some bit, he needs to show that bit existing; whereas con showed that there is no last decimal place for the missing 0.00000000000000000000000000...1 to occur).
Sources:
So the Brit site StudyMath.co.uk bolstered that pro's proofs were valid, and Wikipedia that it was sound, due to people having worked this out long ago.
Con offered nothing, not even a challenege against the authority of that third party verification of pro's case (it's pretty essential on a debate like this, so the absence of it hurts more than the normal dropping of sources).
S&G:
Missing punctuation, capitalization, etc. Here's a gem (pasting a whole round here...): "you are splitting hairs , literally!"
Pro on the other hand was perfectly legible.
Conduct:
Forfeiture from con, no issues from pro.
Offered neg case:
There are two ways con could have conceivably won...
1. Argue that pro is launching a truism, which would make this an unmoderated troll debate.
2. Use the ≈ to demonstrate that while X is effectively 1, it is more true to say that X≈1 than to say X=1. ... Before reading this debate, that would have been my case, but I am now convinced (so it would have been a losing argument to me due to pro's argumentation skill, but it would have been a valid if unsound argument to make, which truly could have turned other voters... and yes, if well argued I could have voted in favor of it even while now disagreeing).
3. As a bonus I would have rejected offhand, a Kritik against our number system for not really existing such as the lengthy one carried out in the comment section. A slightly better one can be found within a single post here:

"Only a number that ends and reaches its endpoint can be deemed an actual number that exists."

This is a made up requirement for numbers.

https://www.mathsisfun.com/sets/number-types.html

Repeating decimals are not only "real numbers", they are ine of the broadest categories. Rational numbers. You made up an arbitrary definition and then got mad...

I have had enough of your bullshit, welcome to the blocklist.

Are you making up definitions?

So, if it's an endless series of 9's then it can't be a number according to your logic.

Only a number that ends and reaches its endpoint can be deemed an actual number that exists. If 0.9 never reaches the last 9, it doesn't exist. 1.0 exists as an actual number the ends and has nothing left to 'reach' other than endless 'nothingness' which is infinite 0's. Therefore, 1.0 is an actual number and value while 0.9r0 is as bullshit of a joke as is the 0.0r1 that differentiates it from 1.0r0

*there is no 9 at the end of the 9s*
Its just an endless series of 9s
Just like the endless series of days til you get your million.

There is no day that you miss your payment. There is nothing at the end of and *END*LESS series.
End-less. No-end. Infinity.

So because the number following all the 9s, is a 9, you carefully dodge needing to admit that 0.9r is impossible and can't exist. On the other hand, you happily point out that the 1 following the 0's can't exist in the difference between 0.9r9 and 1.0r0

If i promise to pay you a million dollars, just wait an infinite amount of days before you get it... will the time ever come for you to get paid?

No you will never get paid. This promise may as well not exist.

Similarly your 1 at the end of infinite 0s may as well not exist. Thus the difference is 0.00..., or 0. And if there is no difference, they are the same.

Thank you for providing me with a suprising extra proof.

forfeits 1 round*** not 2, rest of my RFD is valid

I am reporting Ragnar's vote solely for the S&G part of it.

If 0.0r1 doesnt exist, neither does 0.9r9

Thanks.

Just because you dont understand the math, doesn't mean the math is wrong. Your jibberish algebra and false beliefs about base 2 prove your lack of understanding. You need to brush up on your grade school math. Also, try to watch some videos about infinities.

@RM
There is no end to 0.999... or 0.333...
It literally goes on forever (the definition of a repeating decimal)

Also there is no such number as 0.0...(0 repeating forever into infinity)...1
because the 1 would literally be in the ∞ + 1 digit.
∞ + 1 does not exist

I know how to convert fractions into decimals amd percentages. I know indices, stats, decision mathematics and very much. I also know what is wrong with it.

When you convert 1/3 into a decimal or percentage, you are deep down lying to yourself and everyone else if you don't admit that at the end of the 33333... Is not a 3 but actually is supposed to be a number that doesn't exist that is 1/3. The reason it has to be there is to be the '1' at the end of the difference between 0.9r and 1.0 which is basically what a third multiplied by 3 is causing a hassle between. If you realised that there is supposed to be an actual third itself at the end of the infinite 3s, you'd then realise the extreme conundrum in saying a third exists as a non-fraction at all.

@RM
Did you watch the video?

Binary long division will show you the sham of dividing 1 by 3. It literally cannot.

>>>0.0101.....
11/1.0000
>>>>>>11
>>>>>>100
>>>>>>>11

Binary long division
https://m.wikihow.com/Divide-Binary-Numbers?amp=1

So you're saying 1/3 doesn't exist...

you need math help:
https://www.khanacademy.org/math/arithmetic-home/arith-review-decimals/decimals-to-fractions/v/converting-fractions-to-decimals
(play the video at 1:11)

Rounded to what placeholder?

33.33% to 2 decimal places indeed. The reason being that the 2/3 is rounded to 66.67%

Note how you had to magic up a '7' there to make the system work? That is because of the 'third that tags along' in 0.3r being a third of 1.

0.3r is not a third of 1, instead it is 0.3r followed by '03333....' followed by '0333....' infinitely so. Much like this debate, which is becoming a recurring loop, so is a third of 1 following itself again and again for the 'third of 1' never is actually put into the number at all, it doesn't exist. the number that is a third of 1 is an illusion, a lie, not even a concept but a pseudo-concept. 1 is only capable of dividing itself into all multiples of 2 that are not multiples of 3, as well being divided into as odd multiples of 5. It cannot ever be divided by multiples of 3 or prime numbers.

@RM
Three people are in a room. One person is wearing an orange shirt. What percentage of people in the room are wearing an orange shirt?

talk me through how you divide 1 by 11 in binary, talk me through the first step, by the fourth you'll realise your error.

That is because the pie you are dividing is not necessarily 10 / 1 / 100 / 1000 / 1mil

I was talking about 1/3

If the pie is 9 of a unit in circumference, then yeah you can divide it by 3 like that.

You cant have something at the end of an infinite series. You dont understand the definition of infinity.

So you went from you cant divide by 3 in binary to you cant divide by 3 at all... i can divide a pie into 3 slices. Evenly.

So you were wrong to assume you cant do.something in base 2 that you can do in base 10, can you admit your knowledge of math is limited?

If you declare 0.9r with a 9 at the end possible, then 0.0r with a 1 at the end is possible too (the difference between 0.9r9 and 1.0r0 is 0.0r1)

The reason you never can reverse engineer the 10M bullshit trick is because it's fake. It's an illusion based on pretending 0.9r is a possible number to begin with.

wrong. You cannot divide 1 by three, ever. It doesn't matter what you have, whether it's bread, dollar, anything. Never. Ever.

In poker if there is 10 in the pot to split between 3, they take the 1 from the '4' in some tables (it disappears entirely from play) or in other poker rooms it is given to the aggressor (first to bet for the allin of that split pot).

Never ever will it be split by 3 because only a bullshitter will waste their time telling to divide that. Numbers are fake when they are recurring, it is a flaw of trying to comprehend thigns in denary. In binary you can blatantly see the 1/11 is impossible but you deny that still, it never ever will compute if you try to do it.

To be honest, i didnt understand your proof: S∞ = a/1-r 

You defined all the variables, but not the formula, specifically, whats up with the "1-". Can you. Break it down?

Wrong. I will prove you and PressF4Respect so wrong right now.

Reverse engineer the 10M thing,

do it.

Start with 1.0, you never end up with the fake number 0.9r

THAT IS BECAUSE ONLY 1 is the number, 0.9r is an illusion, a fake irrational glitch in a denary.

A third has no binary possibility. You cannot divide 1 by 3, the binary value would burn your computer chip to process, it would never end being computed.

1/3 in binary is 0.010101...
It exists, and binary is not some pure form. Its just another number base as pure as any other.

https://en.m.wikipedia.org/wiki/Binary_number

Your math is jibberish. If someone says 1+1=3 thats not a math trick, thats someone saying nonsense. Your equations do not follow from each other. They may as well be isolated statements that have nothing to do with the previous or next one.

Your x/y vs y/x is you assuming your conclusion. It is not prove x=/=y.
We started with a single variable, x=0.999... and simply multiplied or divided both sides with the same value. This does not change any equation ever, and the conclusion was that x also = 1. No tricks, just basic algebra. Your math is tricks, your math is wrong.

OMG so my professor said that numbers are just a social construct, and that they like don't even like mean anything in the real world; and they're all like eurocentric anyway so we should um like reject them for like that and stuff. There was this this thing called the three-fifths compromise, which wrongly implied five is greater than three, but we know anyone who thinks that is evil. Our number system was culturally appropriated from the Arabs anyway, so like no one else is allowed to use them, and if you do you're like so totally a racist and a horrible person...
/Satire

If you try do do math in binary (which is the pure form of all math and numerical logic) you will realise that 1/3 doesn't exist, therefore it can't be a number.

0.3recurring is not 1/3, this is a fake thing that you're blackmailed to lie about believing in if you're intelligent enough to realise it's wrong, in order to get marks.

It's disgusting that they do this to you. 1/3 is not a number. It will be 0.3 recurring with a '033333recurring' after the 3's and then that has the same at the end of it, infinitely so.

0.3 recurring never becomes that, so it clearly can't fucking multiply by 3 to make 1.000 recurring. Instead it masquerades as 1/3 while really being 0.9999recurring / 3

That is the truth. It is why I lost the debate, because some voters can't grasp the truth, and that is always how it will be. I have learned to pick debates where I am on the side of easier truth. In time I will show to you all what a sham debating is and yet remain the best at it.
