 0.999...Is 0.999 recurring = to 1?
I think it is but I'm not sure now so id like some opinions. I know it can be proved by: x=0.9recurring 10x=9.9recurring 9x=9 Therefore x=1 And that 1-0.9recurring is just lots of zeroes, so many that the one at the end is so far away that it doesn't exist cos it can never be written. What do you guys think? |

Are you trying to subtract 1 there? _________________ Jey123456 wrote: That will happen in a future closer than most futures.  No Context. Ever. Idaten. |

Re: 0.999... yeah I should have done:
10x-x=9.9...-0.999... to make it more clear _________________ For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. |

Re: 0.999... Yes, they are the same thing. This is not an opinion but the simple fact. To avoid getting too technical in a first post, let me put this to you: two numbers are by definition identical if there is no other number that is greater than one of them and less than the other. You can probably convince yourself that this is the case for .9 repeating and 1.
The proof you posted looks right, but I didn't read it very carefully. _________________ (DefQon1) use a Rhino reconstruotereatarerer - (Pasta) I need to figure out how to get rid of this UrQa Suqqa Ukuk (Bluenoser) Put your finger in your mouth and gag reflex should do the rest |

Re: 0.999... 1/3 == .333...
3 * (1/3 ) == 3 * .333... 3/3 = .999... 1 = .999... There is another way of looking at it. ^ EDIT: Fuck my insertion of excess words. _________________ Fucking loot... Awesome character art by my friend Jee. Last edited by Nuromishi on Tue Apr 24, 2012 12:04 am, edited 2 times in total. |

Re: 0.999... Nah the fractions one doesn't work. There's always something left in the carry. (Whatever the fuck that thing is in long division)
*continues to go through wikipedia's list* Next one up, digit manipulation. No, sorry, again, you have an infinite amount of carrying you did not do. The idea is that the length is infinite. Multiplying by ten doesn't shift it like they want. Subtle difference, like subtraction and differences, one is always positive there, subtle difference, though. Try it in another base. (should be fun, 0.999... in base two, easy enough, right?) And, yeah, all of this hinges on how mathematics treats infinity. You might as well outright state that it's true because math says so. Long story short, the infinite string of numbers part of it is a property of the number and is not supposed to be gotten rid of like that. Kind of like sqrt -1. You can't just skip that(you can if the equation called for difference instead of subtraction though, see relativity for why it matters) _________________ Gaffateip wrote: I love ss forums.

Re: 0.999... Not giving a fuck 0.999 isn't 1, what you gonna do about it?!?
Here's my proof; 0.999 x 2 = 1.998 1 x 2 = 2 Fuck logic  This also counts for 0.9999999x2 etc! _________________ My Characters (to avoid confusion): Xenophanes, Protagoras, Error Message, Aku'Qa and Unfriendly |
