All right, here's a little brain teaser for all of you. It reminds me of a math problem I had around 6th grade. Anyway, it's a Japanese IQ test, and it's apparently given to job applicants in Japan. Click here and good luck! I did finally get it, and I can now go sleep peacefully!
UPDATE....I just went back to the site to retrace my steps and remember what I did to solve it. You know, in case you got stuck and needed a hint or two. Well, I am totally stuck again. So, if you figure it out, let me know! So much for going to sleep peacefully! Dang.
