Abstract

The point of the following sections is to give you a chance to practice the skills from previous chapters on the sort of introductory material basic to, and often constituting the first part of, many upper-level undergraduate courses. You need to learn this material (if you don’t know it already, and a more active style of reading may show you that you don’t know it as well as you thought); you need to practice the skills of active reading and of proof discovery. The point of these remarks is to call to your attention this somewhat unusual double set of goals, so that you monitor your activity with respect to both of them.
