Fundamentals of College Algebra

Course Description

Algebra—or “al-jabr”— literally means the “reunion of broken parts”. The origin of algebra is traced to the ancient Babylonians and is the unifying thread of almost all of mathematics.

This DSST exam was developed to enable schools to award credit to students for knowledge equivalent to that learned by students taking the course. This exam covers topics such as complex numbers, algebraic operations, equations and inequalities, and properties of functions and their graphs. The use of a non-programmable calculator is permitted in this exam.
