Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 Technically an infinitesimal number of 9's is 1. Since mathematically no number exists with an infinite decimal series of 9's... No, it's not rounding because there is no end number to round... Link to comment Share on other sites More sharing options...

Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 Take this - Jimmy is standing in a bus 2 feet from the door.... Every time he takes a step it is one-half as far as his last step. He starts by taking a one foot step. Will he ever make it to the door? (1/2) + (1/4) + (1/8).... ad infinadum = 2, yet if you only go so many steps, not infinitly many, you never reach 2.... Same goes with the number of decimal 9's. PS: If you don't get this, then you'll never get it. Link to comment Share on other sites More sharing options...
Huy Posted May 24, 2002 Share Posted May 24, 2002 let x = 0.99 100x = 99.99 100x - x 99x = 99 x = 1? Link to comment Share on other sites More sharing options...

Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 100x = 99 not 99.99 genius Link to comment Share on other sites More sharing options...
Huy Posted May 24, 2002 Share Posted May 24, 2002 i thought it was a recurring decimal 0.999* x is 0.999999999* 100x is 99.99999999* minus x gives 99x (99, already removing the 0.9999*) 99x=99 x = 99/99 =1 Link to comment Share on other sites More sharing options...
Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 Oh, ok then... You're fine there.... But for the fact that you can't multiply an infinitesimal number by a real number like I said in my pi post.... Link to comment Share on other sites More sharing options...

Bant Veteran Posted May 24, 2002 Veteran Share Posted May 24, 2002 think of it this way. any number divided by X and then multiplied by X is that number. 1/3 x 3 = 1 divided by 3, multiplied by 3. based on this fact.... what your topic should really be is 1=1?!?!!?!?!?!?!?! let x = 0.99 100x = 99.99 100x - x 99x = 99 x = 1? your getting your equation messed up there bubba... x=.99 100x=99.00 100x-x = 99-.99 = 98.01 99x=98.01 x=.99 X can not equal more than 1 thing in an equation. in yours you state it equals 1 and .99..... make up your mind. =) Link to comment Share on other sites More sharing options...
Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 Ok, I'm just gonna put it in simple terms because I'm going to sleep now..... 0.99999999999 ad infinadum doesn't exist so there.... And Pi the number doesn't exist, only the theory of Pi exists, and approximations of Pi 3.14159265358972 {is not equal to} Pi Link to comment Share on other sites More sharing options...

sp00nman Posted May 24, 2002 Share Posted May 24, 2002 I'm a firm believer that there is no such thing as a definite, clean whole number. Of course, if you had 3 tennis balls and asked me how many tennis balls, I wouldn't say 3 because the slightest difference in shape between them all throws it off. Of course, this difference is very minor but it counts. It's hard to explain, and very technical, but just think about it. :old: Link to comment Share on other sites More sharing options...
VaxoP Posted May 24, 2002 Author Share Posted May 24, 2002 evil_dragon, of course u can - pi is irrational, the numbers following one is not in a logical order.. however 0.3333 forever IS in a logical order.. even though it goes on forever. you cannot multiply pi by 3 and get an exact answer, as the numbers are all different multiply 0.33 forever by 3, and you will get 0.99 forever Link to comment Share on other sites More sharing options...
Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 Naturally, no... I would agree with you, but mathematically real clean numbers exist. Link to comment Share on other sites More sharing options...
Evil Dragon Posted May 24, 2002 Share Posted May 24, 2002 But .99999 forever cannot exist because infinity isn't mathematically defined. When trying to prove something like this you'll just end up dividing by 0. When something gets infinitly smaller it can equal something - my Sum example. When something gets infinitly bigger it equals infinity - 1+2+3+4..... When something is infinitly stable it will ultimately lead to infinity - 1+1+1+1+1.....

Bant Veteran Posted May 24, 2002 Veteran Share Posted May 24, 2002 we count things(like tennis balls) by how many of them there are, not necessarily by their weight or size(though depending on the circumstances there are many different ways of measuring quantity). just because 1 tennis ball is a bit bigger or smaller than 1 other tennis ball, it doesnt mean they are not tennis balls. each tennis ball is its own entity, therefore it is 1. >D Link to comment Share on other sites More sharing options...
Prasanth Posted May 24, 2002 Share Posted May 24, 2002 open notepad type 0.999999999999999999 and save it then open notepad again and type 1 and save it now look the first one is 20 bytes and the second is just one byte so they are not equal:P Link to comment Share on other sites More sharing options...
