IN THIS LESSON

Sets, Maps, and Notation

This section is a quick overview of core topics. It gives an accelerated rundown of notation, underlying set-theoretic concepts, and some material on maps.

The information presented here is aimed at those with some mathematical experience at the college level. Although approachable by anyone, those without exposure to some focused mathematical rigor will struggle. It is intended to give a refresher for those looking to explore the other three main advanced courses.

Basically:

  • If this is review, then feel free to jump right into the other topics.

  • If this looks new but you feel you can follow, tread carefully into the other topics.

  • If this looks completely alien, go to 2.1 of this course.

  • Add a short summary or a list of helpful resources here.
