Some interesting brainteasers

Starter

I used factorials for this one, but it will be interesting to see how you attempt your answer.

These questions are designed so that any body above the age of about 13 can answer them without much mathematical experience.

If this is a success then I will reveal the answer this time next week and come up with a new one [MONDAY 28TH DECEMBER 2009]

Brainteasers factorial?

That's the brainteaser.

 Quote by jimmysnyder That's the brainteaser.
Oh, I assumed that there was some math problem that i was missing.
 Mentor There is something missing. The problem is, what is the problem???

Thats what i said.
 Gentlemen, I found the question: http://www.physicsforums.com/showthread.php?t=365013

How did you do this?

 Quote by Borek You've missed the idea - it is not about finding questions, but about finding answers.
Considering how I wasn't sure about how to do the questions

For the first one, I counted. I did use a factorial, but it wasn't a big part of the solution.
For the second one, I graphed a few points and the figure appeared.

What was your factorial (my teacher for pre-calculus didnt teach)?

For the second, doesnt the function go to infinity?
 The second one is pretty much 4 triangles in the four quadrants with vertices (-2,0),( 0,2) ,(0,0) (2,0),( 0,2) ,(0,0) (0,-2),( 0,0) ,(2,0) (0,2),( 0,0) ,(2,0) The area is simply ( 0.5(2)(2)) *4 = 2*4 =8

 In how many ways can the product of the numbers so that the numbers equal 36?
Wow, I have even no idea what it does mean and Jimmy was able to solve.

Edit: what do we know about colors assigned to dices? What color is four sided dice? Six sided one? Ten sided? Twelve sided? Twenty sided? Not sure what types I had, I can't find my set form RPG times.

It is? http://www.wolframalpha.com/input/?i=|y-x|%2B|y|+%3D+2
