The purpose and scope of algebra is discussed in this tutorial with the introduction of relations and their usage. The foundation of higher mathematics is based on algebra because of their relationship to applied and pure mathematics courses.

This tutorial gives an overview of what to look forward to in this course. It also summarizes the most important units and principles in this college algebra course. It is a strong tool to use for anyone who is unfamiliar or is learning college algebra for the very first time. The meaning of VANG is discussed in this tutorial.
