9. anonymous

Any particular type of math puzzle? Geometry? Probability?

10. anonymous

Nothing in particular really.. one of the ones i'm doing, is $x=\sqrt{6+\sqrt{6+\sqrt{6...}}}$

Prove Pythagorean theorem. :D

12. anonymous

I would but we've actually done that too many times now!

Someone else did the question about the childrens ages, where the eldest child has a cat with a wooden leg, if you know that one?

14. anonymous

So a worded problem could be good :)

How about this: a bear is facing south. He walks forward for a mile, then turns right 90 degrees. He then walks forward another mile, then turns right 90 degrees again. He then walks a final mile forward. The bear is still facing south. What color is the bear?
