For most students, a "black-box-input-output" model of functions will suffice. I am, however, focusing more on students tending to proof-based mathematics in their immediate futures. It would be nice if everyone could master these "abstractions" and the basic methods of proof, but few are motivated to do so. I hope my little video and my software will help a bit in this regard.
