This sounds like the first chapter to "The Introverts Guide to the Hokey Pokey[^]." :-D

I really wish that only well-worded puzzles were posted. If this is from a book, please post the full, complete, exact text of the puzzle. Plus attribution would help.

No, that's helping whomever is going to eat the other half moderate their food intake...you're just being helpful! :laugh:

Two questions 1. The context is the first question or the second question ? 2. You mean the puzzle is not clear ? Can you help make it clear because thes are not from any book or text, i read that long back and thought to share

When I sell something 2 + 2 = 5 When I buy something 2 + 2 = 3 more clear than that?

Perhaps the International Puzzle and Gaming Committee should ratify the puzzle, too? :rolleyes:

Oh, yeah, sorry, the second first... the puzzle. I don't find the first second very interesting.

Ah, so you may have left out bits you thought non-essential? Not to get down on you in particular, but any who post puzzles on the Web in general. Plus, many times a puzzle is posted because the poster didn't find the answer, and if that's because he didn't understand the puzzle, then quite likely the resultant post will be garbled and unsolvable. As has been seen on here before. At any rate, of the solutions I've seen posted here so far only ceil(sqrt(22)) seems to qualify as a "proper" answer. The answers 5+5+1 and 2+2+2/2 don't qualify, because they break the implied limitation. If you then say "I never implied that", then the puzzle is no longer interesting, because many many solutions are then possible and a puzzle should have one or very few solutions. How about, "I am one with two plus two, that makes five"? Or, "two plus two and a banana makes five"? When I read a puzzle like that (poorly-worded) on the Web I can only assume that the poster left out such details in the interest of brevity, or not realizing the scope of the error, or because he's smoked too much weed. -- modified at 19:51 Friday 26th January, 2007

i don't think a lot of people here agrees to that, because the question is very simple , just one line and there is no scope of misunderstanding it. i added a bit of confusion to make it difficult to understand on the first place and there is only one MATHEMATICAL ACCURATE solution to it. and i do have the solution to it

Very interesting interpretation though

There are no simple questions, only simple questioners. Well, maybe I've seen too many bad puzzles posted, I'll go read it again.

OK, I reread it again. If indeed

and the only question there is Can a "mathematician in you" also do this ? then, my answer is, "Yes". But that doesn't satisfy

Quartz... wrote:

So, perhaps the answer you seek is, "No". At any rate, ask the question without

because otherwise I must assume you've smoked too much weed.

Math.Round(Math.Tanh(2) + Math.Sinh(2)) is 5 :)

Ist one sqrt( (.2) ^ (-2) ) [^] i can hear your "huh!" 2nd one as some of you have already guessed the mirror just reflect and our eye see the image horizontally . The reason why it appears to reverse left/right is because of the symmetry of our body. nice weekend
