0,999...

Did you know that the symbol/number 0.9999... (nines are repeated to infinity) also represents number 1?
So we've actually got two symbols for one number. Awesome, I know. In fact - as wikipedia states - every nonzero, terminating decimal has a twin with trailing 9s, such as 8.32 and 8.31999.








Cool mathematical trick. Well, it's not a trick, but still - cool. A bit connected to my fractals article.

0.999... Wiki - Check out proofs etc. Skepticism in education is interesting, too.

  2. I've seen many forum topics where people argue about this. some funny moments there.

    could say it's a mathematical feature.

  4. 1 divided by 3 is .33333333333333...

    so that's a third of 1.

    Multiply that by 3, and you get .99999999999....

    So, in essence it works.
