"Choose" operation in math

[sundev]

I need a website or something that can do "choose" operations for me.. anyone know of one??

I know I can do it the long way with factorials, but that takes forever.

It doesn't take forever, as long as the numbers aren't too big. A lot of cancelling out occurs.

I have to do tons of chooses with large numbers.

Most between 25 and 75. And I have to do about... 60 of them.

Agreed. LOTS of cancelling.

Not that I would know anything at all about permutations or combinations, mind you.

Yeah, you're gonna get really large numbers. Search with google to see if you can find a website that does combinations with numbers that large. If you have a calculator, you can always use Stirling's approximation.
