Introduction

Why review topics from earlier math classes?

Leftovers again?

You have been in class all day, running around, picking up your kids from daycare and after a long, brutal commute you get home to realize you haven’t thought about what to fix for dinner. You go to the fridge and all you see are leftovers, a jumble of unrelated bits and pieces from meals past. Despite your fatigue, you manage to cobble together a meal that everyone will eat¬†willingly and get on with your evening.

In this module, you may feel like the topics are a cobbled-together meal of leftovers.  The goal is to give you a reminder of some of the skills and topics from earlier math classes that, like the container of leftovers in the back of your fridge, are easily forgotten by most people. Because sometimes we just forget how these concepts work . . . until we need them again.
