I do that stuff a lot with my elementary aged children, enough that I just assumed it was asking how many rectangles there were, and vomited the answer. Thanks for your supportive vomit analysis though. I guess you didn't notice I edited my answer.

Let it have a competition with us. If we asks, and it doesn't answer, we eats it, Precious.

The number of subsets of {1,2,...,20}, the sum of whose elements is divisible by 5.

Is it tasty? Is it crunchable?

408... always twice as many squares when stoned.

time's up, (2^20+2^6)/5=209728.

What the heck, it was worth a try, you might have been interesting.

as I expected, the answer for this came in private communication. Makes you wonder how many other math nerds there are on this site that won't communicate on these forums. 

Anyway time's up, it's (2^20+2^6)/5=209728. Pwned.  

I think the next word Peyton says is "OMAHA"!!

Well it's pretty simple. If you look at all the different options for squares, you see that every time you raise the number of little squares (there are 64) in a square, you get one less row and one less file. That means the number should be: 8*8+7*7+6*6+5*5....+2*2+1*1=204. That's it.

These cuckoo clocks don't come from an assembly line, (@#$%)es. Each one of them is unique, and is made by hand, right here in the Black Forest.

The Black Forest, is that in the US?
