No. Equal means exact, not infinitesimally slightly different. -- nm - Will Hunting Dec 12, 04:46 1
- But there is no infintesimal difference. - Reagen Dec 12, 06:19
My favorite math puzzle is 2=1. I'll show this to someone at our next gathering. - Strongbad Dec 12, 04:09
If there is a bar over the 9s, I think so -- nm - ty97 Dec 11, 22:23 6
- oh, yes, I was presuming the bar. -- nm - Reagen Dec 11, 22:26 5
  - Fun with math minutiae: do you really need both the ellipsis and the bar? - TFox Dec 11, 22:35 4
    - just one or the other. But pixie's original subject had neither. -- nm - Reagen Dec 11, 22:36 3
      - sorry, i thought the infinite repeating was implied. i could have added more nines -- nm - prisoner 24601 Dec 11, 22:38 2
        
        I think 3...no, 4..more 9s would have convinced the non-believers. nm - ralph wiggum Dec 11, 22:40 1
        
        curse you, 150 character limit! -- nm - mafic Dec 11, 22:48
I knew we'd done this before. -- (link) - Reagen Dec 11, 22:17 [Backboard] 5
- I resisted initially but accepted it after looking at a circle as a regular polygon with an infinite number of sides. -- nm - Max Dec 11, 23:24 1
  - way to stick to your guns, fermax -- nm - prisoner 24601 Dec 11, 23:24
- That was a lot of nerd in one thread. -- nm - David Dec 11, 22:50
- Poor RayRay shouting into the hurricane on that one. nm - ralph wiggum Dec 11, 22:36 1
  - yeah, we didn't even come close to tiny typing this bizzatch -- nm - prisoner 24601 Dec 11, 22:40
Yes. Think about 1/3 + 1/3 +1/3. - Reagen Dec 11, 21:57 8
- My teacher went with 6/9=.6666..., 7/9=.7777..., 8/9=.8888..., so 9/9=.99999.... -- nm - Ender Dec 12, 04:49
- I was like "Reagen is going to beat me to this." -- nm - TFox Dec 11, 21:58 1
  - I just happened to be up. :) -- nm - Reagen Dec 11, 21:59
- three thirds = one whole -- nm - prisoner 24601 Dec 11, 21:58 4
  - right, but one third = 0.333333... - Reagen Dec 11, 22:00 3
    - yeah, but "a whole" = 1 - prisoner 24601 Dec 11, 22:01 2
      - This is one of those things where you really have to grasp infinity. - Reagen Dec 11, 22:04 1
      - it's effectively a rounding error you get by expressing infinite numbers in finite ways. -- nm - mafic Dec 11, 22:04
