Re: "I'm struggling to understand what op-amps do."
An op-amp is just a serious signal amplifier (correct me if I am wrong, but something like 1:100000 straight through...) with a differential input and a simple output. The +/- inputs allow for a negative feedback, so you can easily adjust the gain. You can do all kinds of tricks with op-amps.
