The main objectives of the college algebra series are three-fold:

-Provide students with a clear and logical presentation of -the basic concepts that will prepare them for continued study in mathematics.

-Help students develop logical thinking and problem-solving skills that will benefit them in all aspects of life.

-Motivate students by demonstrating the significance of mathematics in their lives through practical applications.
