So I'm totally new to electronics so forgive me if this question is something easy or in the wrong forum. I'd like to find a way to send math from my raspberry pi to an IC, then have the IC return the value. Does someone have a site they can point me to that shows how to do something like this?

I made a Z80 system once upon a time that used an AMD 9511 Math Coprocessor. It was a stack machine where you sent data and operations and poped the result off the top of the stack. That is 35 year old technology so probably won't be much use to you. The ARM processor is fast enough and capable enough to do whatever you want when it comes to arithmetic and functions.

I suppose you could implement an AmD 9511 Emulator if you have the stones to code it.

Thanks for the replies everyone. It's not that I really need the extra chip. It's more of a learning tool as I'm just curious. I asked on the pi forums and they didn't have much to say so I thought I'd try here.
