Yep, I think we have one, but this is for those who need math questions answered, or needs homework help or something like that. I don't know where to put this topic, so I stuck it here.
My question:
How do you write a compound function?

If anyone's willing to help me out on a seven page essay on Shakespeare I'd be happy for them to give me a hand

Either f(g(x)) or fog(x). Both notations are used.

Actually, I was thinking about making a topic like this in Maths today
I found an awesome way of doing long multiplication without a calculator XD

Yeah, I also learned how to multiply a very easy way a long time ago. Perhaps we use different techniques though. I use the Nappiers Bones method.

I believe it's called looking at the back of the book where all the answers are.

The people at my school have become dependant on calculators.

I meant the answer has to be <100.
