4*6 = 24
3*6-1 = 17
It never says that all numbers must be used ... :rolleyes:
Well, you have to use all the numbers that were given. And make the calculus in decimal base... :D
Well, that wasn't part of the initial contract ... :p ;)
have to start everything again ...
(6-(1/3))*3 = 17
(5*6-1-4)-- =24 :p
Well, master Elrond you got this one. :thumb: So As the "initial contract" said you can solve only one of them you win it and can ask the next question...Quote:

The soul! Because it's trapped in the body when I'm alive (hence fixed) and free when I'm dead, (hence mobile).
Nope, it might be a tree. It's fixed until someone cuts it off... then it's moved to the factory for futher processing.
Save trees!
Nope, at least until it is proven soul exists and that it leaves the body at death time.
Well, a dead tree usually stays where it is.
An apple. It's falling from a tree when it's dead. Falling is a kind of moving too. Then it can be rolling downhill for some time (but U didn't point out that it should be moving all the time).
ops I know, I know that this's not the right question. :D
ok, you're close, but there's a better answer.
Tumbleweed
What's that ?
A plant native to the western US that breaks off and starts rolling across the great plains in the wind. It is the plant's way of distributing seeds.Quote:

From this article it is also called Russian Thistle.
Well, I guess it works, but the answer is more common knowledge: tree leaves.
Find four distinct integers such that the sum of every two and the sum of all four are perfect squares.
Let me know if if got it right.
The problem is: found for integers, a1,a2,a3,a4 for which the following conditions hold:
1. Whatever a,b from {a1,a2,a3,a4}, a+b = perfect square
2. a1+a2+a3+a4 = perfect square
Do you mean natural numvers (>0) or integers that also can be negative?
Natural numbers -> >0Quote:

No such 4 numbers lower than 1000. Perhaps I'll let my PC run over night and check it to 1,000,000 but don't like this question any more... :(
There is an answer with all 4 numbers <11000
With 4 distinct numbers i,j,k,l for which
i+j+k+l = perfect square
i + j = perfect square
i + k = perfect square
i + l = perfect square
j + k = perfect square
j + l = perfect square
k + l = perfect square
?
No, there isn't...
Yes there is. :eek:Quote:

Here are the numbers:
386 2114 3970 10430
I have to say thank God for the Athlon 1800+
This was a tough one... :eek:
Of course, a computer can solve that problem, another case if U can solve it using just your mind ;)
Let's get real... that problem cannot be solved by human brain in a reasonable time... at least not by mine :D
Given the result, I think it would have been a tough one to solve without a computer ... There might be a way, but i am not even sure i want to hear about it ... :rolleyes:
Give a representation of 100 with 9 digits in the right order (i.e. 1 goes before 2, 2 goes before 3 and so on) and math operations in between.
Simple example: 20 from the first 4 digits: 1 + 23 -4 = 20.
For the problem you have to use all the 9 digits from 1 to 9.
I wrote a C program and had it crank out the answer in less than 15 minutes total. It wasn't that hard. I have a really old 750Mhz computer here.Quote:

Red moves down. White moves up. The 'Kings" can go either direction.
Red has a move which forces a win by removing all of whites pieces. (after a sequence of several forced moves.)
Just one question. Who goes first? It sounds like you are saying red goes first in this problem but in the previous problem you said white goes first. I just wanted to check.

Well done. You get to ask the next question
Okay here are the rules.
-You start at the yellow square.
-You must walk on each red square.
-You cannot walk on any square you have already walked on.
-Blue squares and black squares cannot be walked on.
Extra credit for anyone who can tell me what this is from.
Good luck
-Ben
Here's the solution, though I have no claim to your extra credit:
Looks good. This comes from the little game called Chips Challenge. If you have not had the chance to test your logic skills with this game I highly recommend it. You can find free downloads on the net. So what's the next question?
-Ben
We are expecting a question from SolarFlare.
Solar seems to have dropped the ball. Again....
Let me guess, his excuse will be that he couldn't show up for the mandatory dope test because he was in a motor cycle accident?
Hope not, since these kind of bad stories gets you banned. :sick:
I say we give SolarFlare 48 hours, starting now, to come up with a question. Otherwise the last to answer a question here, gets to ask the next.
Well in Solars defense...it's football time...and those philly peps can get a little wacky with the tacky...
/Know what I mean
