Sorry, the correct number is: 3816547290
The other will not work with 8...
Why? because it follows the rules.
3816547290->
10 * 381654729 = 3816547290
9 * 42406081 = 381654729
8 * 4770684 = 38165472
7 * 545221 = 3816547
6 * 63609 = 381654
5 * 7633 = 38165
4 * 954 = 3816
3 * 127 = 381
2 * 19 = 38
1 * 3 = 3
I just wrote a little program to find it ;)
Even without that, there are a few rules that would make it easier:
The last digit MUST be 0 (divisible by 10).
The 5th digit must therefore be 5 (first five divisible by 5, and 0 is gone).
You only care about finding the correct number up to 8 (if you follow the rule of having only different digits, you have 0 as the tenth, so when you end up with the remaining 9 digits, all numbers can be divided by 9, if you remember the rule that when the sum of the digits can be divided by 9, the number can be divided by 9).
Every 2nd digit must be an even digit (must be divisible by an even number).
I have not found any other rule yet, but it already reduces by a lot the number of possible answers... (about 2401 left if I am correct, but might not be as I am not that good with statistics).
Serves me right for trying to stump people with a question that can be solved by brute force. I was kinda hoping for something a little more elegant.
All right, Elrond, ask away.
Is there a more elegant solution? Probably yes, I'd like to know it. :)Quote:

I am about to leave and have no time to find a riddle now. Anyone who wants can ask one. Otherwise I'll try to find one tomorrow :cool:.
Fine, I'll ask one that can't be solved by brute force, hopefully none of you have read it before:
Arrange a group of 4 numbers such that with the addition of some symbols they form the two sides of an equal equation. For example: the numbers 3,4,6,9 can form 4*9=36. Okay? The numbers in question are: 2,4,7, and 9.
Too easy?
Do you want to try a riddle in the style of SeventhStar?
Well, you have to look for a password hidden in the attachment.
There is a 'poem' which will give you a hint for knowing what to do with the attachment.
I think this is very easy.
Read carefully and sorry for the bad english.

Come here and read.
Here is a riddle again.
After finding the password,
no problems will remain.
Gurus and not gurus can try and
easier riddle will not find.
The first thing you should do is the
hint find.
Extend your mind,
search for the hint to victory.
Extend your mind,
code is the solution.
Observe as well as you can and
none of the hints will hide.
Delicate the hint is, so
you should read carefully.
Extend your mind,
look at this text.
Look at the attachment.
Obviously you are a
Winner...
:D

Hmmm...I must have forgotten something, because that's not the original answer.Quote:

Well, you did it using 2 symbols (plus and minus), can anyone do it with less? I can :) In fact, I can do it without using any symbols at all...
Well, I'm not sure about what counts as a symbol here, butQuote:

47 = 2 (mod 9)
if that's the kind of thing you were thinking...
'mod' counts as symbol. In fact, forget symbols completely - just have an equal sign.
You know, this riddle would have been much better if I had gotten it right in the first place.
Yes, but think of the satisfaction you got from throwing your keyboard around the room for a while.
That is 7 squared = 49Code:2
7 = 49
*Every even digit must be even (even # multiplied by anything is even)Quote:

* And consequently every odd digit must be odd
Well I found the hint, but I don't know what it means.Quote:
