The man who invented it doesn't want it. The man who bought it doesn't need it. The man who needs it doesn't know it. What is it?

Re: Puzzles
There's at least another word pronounced differently if initially capitalised. I'll give a clue as to the one I'm thinking about: it starts with the first letter of the alphabet.

Re: Puzzles
I've thought of a possible answer but don't want to dive in until others have seen the question. If I am correct it's a very distinguished solution.MSoszynski wrote: ↑Thu Mar 11, 2021 12:42 pmThere's at least another word pronounced differently if initially capitalised.

Re: Puzzles
I don't know if we are limiting ourselves to word puzzles but this is a fantastic Maths Challenge.
Using the numbers 2, 4, 6 and 8 and the simple operations + - x / ( ) Make 25 (obviously you can only use each number once)
It is a pure Maths problem, there isn't a silly trick.

Well done! It's one I noticed myself rather than reading about it somewhere.Kevin Williamson wrote: ↑Thu Mar 11, 2021 7:00 pmMy answer to this one is august/AugustKevin Williamson wrote: ↑Thu Mar 11, 2021 1:08 pmI've thought of a possible answer but don't want to dive in until others have seen the question.

Re: Puzzles
OK, let's look at the prime factorizations of those:
-101250000: - (2^4 * 3^4 * 5^7)
-1728000: - (2^6 * 3^3 * 5^3)
-4900: - (2^2 * 5^2 * 7^2)
360: 2^3 * 3^2 * 5
675: 3^3 * 5^2
200: 2^3 * 5^2
Nothing obvious springs out there.

Re: Puzzles
Bearing in mind it is possible to fit a polynomial of degree 6 through 7 points you can offer any number as the solution. You could also overfit the data and produce any number of polynomials. This means that all those IQ tests we were forced to do as kids were all flawed on this type of question.John Upham wrote: ↑Thu Mar 11, 2021 10:30 pmWhat is the missing number in this sequence:

As this is a chess forum, I think you should have chosen the chess puzzles from the same set of questions:John Upham wrote: ↑Thu Mar 11, 2021 10:30 pmWhat is the missing number in this sequence:

Indeed. The very item that The Dancing Outlaw (Jessico White) told his wife in a documentary she would be going to sleep in if she didn't cook his eggs properly...as you would

Here's a top puzzle that's as tough as chess (sub 2800 ELO rated players need not attempt it): Who hides in the bakery at Christmas?
