OT: "82" puzzle
Standard QuickSand disclaimer: I didn't create this puzzle, but I like it.
Standard Maple Leafs disclaimer: Every time I post a puzzle here, someone points out that they've already seen that one, it was posted back in June of '99, etc. So this puzzle is exclusively for people who haven't seen it already, OK? Not everyone has been on the board since the beginning, Methuselah. ======= This is a famous problem from 1882, to which a prize of $1000 was awarded for the best solution. The task is to arrange the seven numbers 4, 5, 6, 7, 8, 9, and 0, and eight dots in such a way that an addition approximates the number 82 as close as possible. Each of the numbers can be used only once. The dots can be used in two ways: as decimal point and as symbol for a recurring decimal. For example, the fraction 1/3 can be written as: Code:
Code:
The Question: How close can you get to the number 82? |

Very well done. Actually, that's not even the answer I had, so you get bonus points.

Cool. I think I'll let someone else come up with whatever the other answer is

Well, by the strict rules: "Each of the numbers can be used only once."
Since they 'can' be used only once, it implies you don't need to use them all... although if that was the case, then:
Which equals 81.9999..., mathematically equal to 82. Of course, that only still leaves 4 periods and two numbers, so I know I'm wrong. Kevin Last edited by Celeval : 02-27-2003 at 01:55 PM. |

P.S. Shouldn't you be off rigging another playoff series? |

Without looking at cuervo's answer above, I got something VERY similar... :P Code:
Ugh.

Re: OT: "82" puzzle
Neat puzzle.. sorry I basically missed it. We certainly could derive new ones based on basically the same concept, though.

To me, this does more than "imply" you have to use all seven numerals, it flat out says so. Last edited by QuikSand : 02-27-2003 at 03:48 PM. |

Oh yeah, I guess I could have posted that too; I figured they were basically the same as flipping the last digits like that will I think always yield the same result (something transitive going on there). |

Other correct similar answers:

Just a matter of flipping digits around, like cuervo said.

You know, I confess I didn't work through this problem... but think about it. $1000 in 1882 was a boatload of money... someone got that kind of cash for solving this puzzle? There really isn't all that much to it, seems to me.

That's what I was thinking. If I could solve this, then anyone could! I'll be expecting my $1G in the mail shortly.
