The Puzzle: Here is a famous prize problem that Sam Loyd issued in 1882, offering $1000 as a prize for the best answer showing how to arrange the seven figures and the eight 'dots' .4.5.6.7.8.9.0. which would add up to 82 @Kevin

:D

OpenStudy (brainzonly):

the dots are OVER the numbers I think it means that it is a repeater which would go on for ever

OpenStudy (brainzonly):

I'm talking to myself, aren't I?

OpenStudy (brainzonly):

My book rates this one's difficulty as 5 star... :DDD fun! @Kevin Where are you? u'r missing out on the party

OpenStudy (kevin):

I'm here :D

OpenStudy (kevin):

OMG

OpenStudy (brainzonly):

Isn't this one fun? Okay, now don't let your brain complicate things :D that will make it worse. Brain teasers are my FAVORITE!! there's a reason all my friends call me The Brain :D (real life, of course)

OpenStudy (kevin):

Lol

OpenStudy (brainzonly):

Wait! got an idea... The dot over a number signifies that it is a repeater which would go on for ever, as when we endeavor to describe 1/3 decimally as 0.33333 . . . . (etc) With a series of numbers we place the dot over the first and last, as with 0.97979797979 . . . (etc)

OpenStudy (brainzonly):

Sooooooo............... The remarkable feature is that a proper fraction divided by 9s e.g. 46/99 is exactly equal to the numerator with the repeater sign followed by the decimal.... and it DOES add up to 82!!!! O.O :D Solved!

OpenStudy (brainzonly):
