Hello, im bored its christmas eve im at work, and im work again on boxing day, so i thought id post this, although no-one will answer it because yopu have better things to do... like... enjoy christmas.

Two guys are playing chess they both play ten games, and win 10 each, they do not draw, tie or whatever. how is this possible?

Any thoughts.....

Ok, here's another one:

What starts with an 'e', ends with an 'e' and contains only one letter?

[korkus2000]

is it an envelope?

[Sinner_G]

Was it that easy or are you that good?

Ok, next try:

How many cookies can you eat on an empty stomach?

[Mike12345]

What cheese is made backwards?

>What cheese is made backwards?

Edam? MADE <> EDAM

>How many cookies can you eat on an empty stomach?

One? After the first your stomach would no longer be empty!

Go for it Blob, your on the ball today arent you? :) Ill have a double of what youve had :)

OK - this is one of my favorite Maths puzzles:

1 1 1 = 6
2 2 2 = 6
3 3 3 = 6
4 4 4 = 6
5 5 5 = 6
6 6 6 = 6
7 7 7 = 6
8 8 8 = 6
9 9 9 = 6
10 10 10 = 6

Using any (within reason - no fancy theorems please!) mathematical operator, make all the above statements true.

EG: 2 + 2 + 2 = 6

Have Fun!

Can I get half a point for solving 5 out of 10?

What about Perl operators, would that be ok? :)

[korkus2000]

(1+1+1)! = 6
2+2+2 = 6
3*3-3 = 6
[square root]4+[square root]4+[square root]4 = 6
5/5+5 = 6
6*6/6 = 6
7-7/7 = 6
8-[square root]([square root](8+8)) = 6
[square root](9*9)-[square root]9 = 6
(0!+0!+0!)! = 6

no square root character :(

Hey Korkus, explain the ! to a history major.

Factorial
[mathforum.org...]

(1+1+1)! = 3x2x1 = 3!
also the factorial of 0 is 1.
(I hate 0 by the way)
like figuring the odds of the lottery.

BTW I can't do 10 10 10 = 6 whats the answer to that?

[Made In Sheffield]

For 10 10 10 = 6

Using logs to the base of 10:

[square-root](([inverse-tan] (log 10)) - (10 - (log 10))) = 6

[Made In Sheffield]

For 1 1 1 = 10

deleted, already solved, missed it

[Go2]

Another solution for 10 10 10 = 6,

(log 10 + log 10 + log 10)! = 6

[BlobFisk]

Hey all,

Apologies for getting back to this so late - but Korkus is on the button! Most people have difficulty with the factorial solutions (1 and 10), and go2 spot on using log to the base 10 for the three tens!

Nice going!
