0.999....(recurring) exactly equals 1 by Inchbrook Posts by this user 34 Date: 24/11/2014 Time: 11:48:56  [Report this Post]   Not so! .999 recurring 1, therefore does not equal 1.  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Inchbrook Posts by this user 34 Date: 24/11/2014 Time: 12:23:13  [Report this Post]   This should have read .999 1 [is less than 1]....  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Anonymous Coward Date: 24/11/2014 Time: 12:37:17    I don't know what you mean. 0.9 recurring, ie 0.999999999999999999999999...to an infinite number of 9s. It equals 1. What are you trying to say?  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Cliff Pilchard Posts by this user 40 Date: 24/11/2014 Time: 16:30:16  [Report this Post]   9*(1/9)=0.999.... No it does't !  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Anonymous Coward Date: 24/11/2014 Time: 17:49:35    what I mean, Cliff, is that 9*0.111..... can be written as 0.99999999999999......etc which is 1.  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Inchbrook Posts by this user 34 Date: 24/11/2014 Time: 18:49:37  [Report this Post]   It's *nearly* the same, but it's not 'exactly the same'. It's like saying 9 is exactly the same as 10, which it patently isn't!  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Anonymous Coward Date: 24/11/2014 Time: 18:57:23    so if you take 0.999.... away from 1, what do you get?  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Anonymous Coward Date: 24/11/2014 Time: 19:02:20    and it's an infinite number of 9s....I should have been more clear in the OP. If 0.999... and 1 are different numbers then one minus the other should give you the difference....and what is that difference?  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Cliff Pilchard Posts by this user 40 Date: 24/11/2014 Time: 22:20:18  [Report this Post]   Quotation: 9*0.111..... can be written as 0.99999999999999......etcwhich is 1
No it isn't. 9x0.1111111...inf = 0.999999...inf which is less than 1 the difference is 0.00000...with an infinite number of zeros followed by a 1  which is impossible because there is no end to the line of zeros as they are infinite. But wherever that line ends that is the 1 that makes the answer smaller than 1. Its the same reason you want your penny change when you spend £19.99 £19.99 isn't £20.00  >> Tagged as: Select All 
0.999....(recurring) exactly equals 1 by Anonymous Coward Date: 24/11/2014 Time: 23:01:40    so if an infinite number of zeros 'ending' in a 1 is impossible, all you have is an infinite number of zeros surely?  >> Tagged as: Select All

0.999....(recurring) exactly equals 1 by Cliff Pilchard Posts by this user 40 Date: 25/11/2014 Time: 09:24:58  [Report this Post]   That's correct  bit like the universe  you keep going up and up and where do you end up ? There is no end you just keep going. If there is a big brick wall at the end of your infinite distance journey there is another side to that wall you break through and you just keep on going, on and on  impossible !
