There was mathmatical proof for 1+1=2! http://mathforum.org/library/drmath/view/51551.html Well, it's not crazy, but it is crazy  |

| Why would you need proof of this? And I think this is the same guy who debunked the .999~ = 1 theory. Of course anyone who believed that in the first place should go back to pre-school mathematics. |

| You can't do a ~ = in the first place... I think the only time you're even allowed to do a ~ is when it involves PI. And you want to know my proof for it. You take one apple, then decide to take another apple. Having taken no apple's previously, how many apples do you have? Or, what is the word we use for the whole number above one, but a whole number below three? |

| .999... = 1 x = .999... 1000x = 999.999... (999.999...) - (.999) = 999x = 999 .999... = x = 1 |

| Besides, the line ".999... = x = 1" really breaks the rules of Algebra. That formula don't prove anything. Talk about taking a mathemtical detour there. xD |

| As I said ~ should only be used when dealing with PI because of the infinite decimimal places. | |||

| Actually, 1 + 1 = 10, isn't it? Also: take 1/3 1/3 = .333~ 1/3 * 2 = 2/3 = .666~ 1/3 * 3 = 3/3 = .999~ = 1 Not exactly proof either, but it's good enough for me.  |

Originally posted by Dracoon I bet you didn't even try to look at it and examine it. You see, if x = .999... then 1000x = 999.999... You subtract x from 1000x that is 999.999 - .999 and you end up with 999x = 999 |

Originally posted by Kitty Jedi This does not "break the rules of Algebra". You see stuff like this all the time. However, Graviteh's first line ".999... =1" is not necessary in the proof, since that would be assuming what you wish to prove. And the stuff about proving 1 + 1 is actually necessary b/c you need a formal system to describe something. Mathematicians don't deal in "Well it seems this way so we'll just say it's true." Rather than putting it in terms of addition, it characterizes the integers in terms of a "successor function", a very important concept in advanced math. Specifically it employs the Peano axioms (when you use them it's called playing the Peano.) Also, .99999... = 1 b/c if you had a sequence .9, .99, .999, .9999, ... this is a monotone increasing sequence with supremum = 1, hence it converges to 1.

| I hate math. It's supposed to be all super and accurate but it's one of the most inaccurate "sciences." I mean, sheesh, we can't even cut ten in to three even parts. | |||

| Yes we can. Just pick a different base. The problem of 1/3 being repeating is relative to the fact that 3 is coprime with 10. We use base 10, that is the problem. But in any base system you fill find numbers that share no factors with the base. e.g. in base 3, the representation for 10 is 101. ( 9 + 0*3 + 1). And the representation for 3 is 10. so 10/3 would be represented as 10.1. Notice, no repeating representation. And never call math an inexact science. It is the most exact science you will ever find. You cannot disprove known results in math, but you can disprove theories in physics, chemistry, biology, etc, if you find the proper evidence. |

| *pauses* *takes a CD case* *takes out another CD case* *puts the cases side by side* One CD case... two CD cases. Proof enough, no? (Mathematicians... always trying to prove the most simple concepts that we take for granted.) |

Originally posted by FreeDOSOriginally posted by Darth Legious To say that 1/3 is equal to .333~, it would have to hold true in reverse. .333~ is not equal to 1/3 obviously. It's the same arguement as .999~ = 1. It's gets close, but never actually gets there. The reason you say everyone holds that to be true is just that it's commonly accepted. It's so insanely close that it really doesn't make a difference if you use it that way. But in a technical sense, 1/3 does not equal .333~ |

| .999~ = 1 is comparing .999~, which is an infinte number, to 1, which is a finite number. An infinite number can't be the same as a finite number, it's that simple. | |||

| Asking some people to understand something that simple is like asking some people why they voted for Bush. You never get an intelligent answer. It's like how some people say, 1/3 = 0.333, 2/3 = 0.666, 1/3 + 2/3 = 0.999 = 1. But 1/3 + 2/3 = 3/3, and 1/3 != 0.333, nor does 2/3 = 0.666. 2/3 is closer to 0.667 than 0.666, and in which case, that whole argument is moot, anyway. |

Originally posted by Darth Legious Then you're not seeing the number as it is... the little tilde (~) indicates that the pattern repeats. In mathematics, it would be a bar over the digits. However, that can't be done in HTML (I could make an image, but that'd be pointless). .333~ will be the same as .3~ or .33333~. It does not mean 333/1000. Originally posted by The Gamorr Z You're confusing infinity (which is not writtable except for a sideways 8) with an infinite number of digits. |
