Riddles =)

Who doesn’t love a good riddle? I think it is safe to say that riddles are something that everyone can enjoy to try and figure out. Today I stumbled across www.riddles.com…, a brilliant collection of tons of riddles and brain teasers. One of my favorites is, “There is an ancient invention that allows us to see walls that is still being used today, what is it?” Well it would be no fun to just post the answer right here where everyone could see right away so how about after you try to figure it out, head over to the forums, join the community, and click HERE to see the answer and join in on some discussions.

Here is one more riddle to keep you thinking, well more of a logic question.

The following is what seems to be a mathematical proof that two equals one. What’s wrong with it?

a = b
aa = ab
aa – bb = ab – bb
(a + b)(a – b) = b(a – b)
a + b = b
a + a = a
2a = a
2 = 1
