 Obviously it does No it doesn't I can prove it I disagree but can't prove it This is so confusing

Obviously it does
Technicalities. 3(1/3) = 0.999999, but by the laws of maths it also equals 1. Therefore 0.999999 = 1.

here is how I see it...everytime you add another 9 after the point the number is becoming smaller and closer to 1. However i the point of infinty (recurring in this example) is that it never reaches 1. Eg working the opposite way.... if you halve something, and then halve it again and again it wouldn't just evaporate and disappear into nothing (well eventually to the naked eye it would). It would just keep getting smaller and smaller forever. Prove against this notion if you can

It's one of the intricacies of maths that you just have to ignore the reasoning and accept it. But yeah, basically seeing as it is infinite, there isn't any actual difference between the two numbers, as 1-0.999999999999 is indeterminate and basically the same as 0.
• Nezkeys79 Anonymo... 2012/07/09 03:00:31
It's not. You can add as many 9s on as you want. The number will never reach 1

What's 1-0.99999999999999...? 0.0000000000000... As there is never an actual number at the end of it, it is the equivalent of 0. 1-0 is 1.
• Nezkeys79 Anonymo... 2012/07/09 14:16:52
Eh? What do you mean there is never an actual number? Of course there is. You lost me at "ignore the reasoning"
• Anonymo... Nezkeys79 2012/07/09 14:56:20
It's not an actual number. As the zeros in 0.000000000...1 never end, there is never any 1 in it, therefore it's just zero. Therefore the difference between 1 and 0.99999... Is zero.

0 is 0. ive never argued that 0.00r is not 0. That's a pretty dumb thing to write anyway. And the difference between 0.9r is 0.1r
• Anonymo... Nezkeys79 2012/07/09 16:15:47
No. You are not getting it. 1-0.9999999 does not equal 0.111111. It equals 0.000000...1. Except as the 0 is recurring, it never reaches the one, and so the 1 only exists in theory. Therefore, it is actually 0.

You just said the same thing...I got it the first time. I refuse to accept the notion that suggests some numbers don't have their own identity...no two numbers are the same
• Anonymo... Nezkeys79 2012/07/10 09:00:18
0.999999... Is equal to 1. Same with all the integer values, so 3.9999999 is equal to 4.
