That's good stuff; Thai stick??
How Many Squares Are In A Chess Board?
no that was what a cuckoo clock master in Germany told me when I offered to give the one I had chosen to another American tourist, saying I would pick up another one. That torqued him off for some reason.
Why do you ask?
I just knew a lady by that reference...
"How many sqaures are in a chess board?"
This is a question that I do not know.

sqaures?
There are infinitely many squares on the board, since the OP didn't specify that the squares had to have a different color inside and outside the boundary of the square. Even a1 alone contains infinitely many squares, unless you believe size only makes sense as a concept down to a certain scale (the Planck length, perhaps), in which case there would not be infinitely many, but still many more than you can shake a barrelful of monkeys at.
The number of subsets of {1,2,...,20}, the sum of whose elements is divisible by 5.
Is it tasty? Is it crunchable?
If anyone wondered how to get this, use fifth roots of unity on (1+x)(1+x^2)...(1+x^20)
because you want to add up all the coefficients - but only if they belong to an exponent divisible by 5. This isn't strong elementary school like the squares question, it's more like strong high school.

6000.
I don't believe that.
Hmmm... oh well... I tried.

Aha! cool.
