    No, I don't accept it because I think the "laws" of math are exploited to come to this decision...

    lol, you make it sound like a moral crime. Sorry its not, its math pure and simple.

    Tell me, what law would you propose so this crime doesn't take place? Ignore infinity? Well there goes calculus...

    The inner nerd in me sparked to life when I read the title! Then died again as I realised the proofs were already posted.

    No argument .999...... = 1 as the proof has shown, santa nicely done trying to trick us with your "recurring decimal" rubbish, which is exactly what it is... the proof is valid.

    The question is, what happens if you do 0,99999*10? Will the infinity become one shorter, or will the infinity create a new digit or what?
    I made a new script, check it out!.

    .9^ * 10 is 9.9^

    SCAR Code:
    const
      InfiniteSymbol = '^';

    lol, if you think that infinity can be one shorter then you truly don't understand it. infinity - 1 == infinity * 10. There is no difference. What does matter is how fast a function goes to infinity, but that's another topic.

    Two ways to write the same number? Are you drunk? And calling us average Joes? I'd really get an ego-check if I were you.

    By the way, stop mentioning people who might have done calculus...because I have done calculus, and I can assure you that I'm more knowledgeable in it than you are.

    What proof? Multiplying by 10 and then subtracting? The proof is invalid. There's a difference, but it can't be written on paper. Do you so-called geniuses feel happy now?

    There is not a difference.


    Show me an equation to go from .999... to 1.

    Exactly. There is no difference.

    Did you read what I said? It can't be written on paper, but there has to be a difference.

    If there was a difference, then it could be written on paper.

    The difference between 5 and 6 is 1.

    The difference between .999...and 1 is 0, simply because you can't go from 1 to .9999....

    If there's a difference then it can be written on paper? Right...

    So how do I write 0.9999, with infinite 9's? Add a dot on top of the first 9? Great. I'll add two dots on top of the second 0 in 0.01, symbolising infinite 0's. Agree?

    but you can't have an infinite number followed by a number.

    Because the 0's would never end, not allowing the 1 to show up.

    Infinite means never ending. It can't be followed by a number, since it will never end.

    1. Lol, and I can almost absolutely assure you that you aren't more knowledgeable in math. I am near a math minor at Uni.. Gee, I just might know something about math....

    2. You say I am egotistical, yet you are the one that is saying that pretty much the entire math world is wrong without providing any proof what so ever, except for saying "It feels wrong, there must be a difference." Guess what, there isn't one.

    3. I say average joes because most people here are under 16. Yes there are a lot of accomplished 16 yo's, some may even have a better understanding of math then the average joe, but most have not had the math classes/opportunities that the average joe of 21+ has had. In essence, I am treating 16 yo's as 21 yo's, I do have a fair amount of respect for them (if you are not 21, that's fine, you are probably an above average joe).

    4. You say this is all Puesdomathmatics, How so? Because what you see or feel can't be written on paper all the sudden your logic becomes infallible? Sorry, but sometime the counter intuitive answer is the right one. I question your calculus because you should know that the right answer can't always be intuitively understood. I question your calculus because the 1 = .999... proof is one that is done in most pre-calculus classes and is a proof that should have been reaffirmed by any good calculus teacher. The reason behind this is because this proof teaches us an essential understanding of what infinity really is.

    Yes, I feel somewhat knowledgeable about mathematics, but that would be because I have taken several upper-level math courses. I have proven my argument and the only response you can come back with is "It can't be disproven on paper" Well, guess what, That's baloney. Had you taken (and done well at) a calculus then you would have known that from the countless proofs that you should have done.

    So again I ask, disprove it. Show where any math rule was broken. But again I warn you, everyone with a PhD in mathematics accepts that .9999...=1, so it isn't just some random guy on the internet telling you this, it is the entire mathematics community as a whole.

    I have never met a person in real life that did well at calculus that would argue that .9999... != 1. I have only ever met people that didn't understand the concept of infinity (and hence don't understand calculus) that would argue against it.

    I agree with boberman, as I stated earlier, my math professor with PhD in mathematics, says that 0.999.... is in fact equal to one.

    Omg. Boberman. You are t3h secks.

    If I knew where you are, not only would I shake your hand.
    I would lick your ear.

    I'm thinking that infinite is confined by time. In the the time it takes 0.(infinite)9 to reach 0.99999, 9.(infinite)9 would only reach 9.9999, meaning that the difference is 1 div (10 ^ infinite). For each loop through of infinity, the difference between the two is decreased by div 10, but is still a difference. If infinite is not constrained by time, then this is irrelevant, but is still my opinion none the less.
    By reading this signature you agree that mixster is superior to you in each and every way except the bad ways but including the really bad ways.

    Well I am a science dude. Anything related to Chemistry, Biology (to an extent physics as the entire concept of universal membranes is amazing) is what I can answer.

    I did do extended/further maths but that was all Hyperbolic functions and rubbish. In tis case, I would just stick two dots about the number following the decimal lol

    Okay, so this is accepted by the math world, but it is based upon, since .999... never doesnt reach 1, it must be the same thing? that doesnt make sense to me, but if it is accepted then it must be true

    It's not that it never reaches it.

    It's that you can't go from 1 to .999...

    It is based on the fact that there is no difference between 1 and .999... . Difference is the remainder of the subtraction of two numbers. So if you take 1 and subtract .999... the remainder is 0. When you have 0 difference between two numbers, they must be the same number. The proof that this is so have been listed several times in this thread.

    Infinity and time are two completely separate and different concepts. Time doesn't effect infinity and infinity doesn't effect time. Its like saying the sky is blue because it's October. Or saying apples taste good because bananas are yellow.

    .999... isn't propagating at any speed, it is already infinitely long by definition.
