Ive never been taught functions using sets and I have been told that to really understand the real meaning of them it is helpful to work them out and understand them with sets and stuff. Im not sure if im on the right track or confused but Im sure someone here can help me out. I have a basic understanding of sets and elements and all that so i should be able to follow along.(adsbygoogle = window.adsbygoogle || []).push({});

thanks in advance.
