Remember my post *Barbie was right, math IS hard-? I showed an example of a mystifying public school math problem, and then I mentioned a stumper from Demi's Math-U-See...

You can go look, I'll wait...

Anyway, the blogsphere is such a funny place- I found a comment yesterday in my mailbox, from the author of the infamous sandwich problem! She admitted she's gotten some flack about it, and also some confusion from the U.K.

So, I have to know....Is a hamburger a sandwich, or not?
