Course Summary

Math is everywhere. In this class, you’ll gain an in-depth understanding of algebraic principles, many of which you may have seen before, and learn how to use them to solve problems that we encounter in everyday life. The online version of College Algebra will cover all of the topics that you would see in more traditional class formats, but it will present the material in a way that we hope you’ll find fresh and interesting. You will learn about functions, polynomials, graphing, complex numbers, exponential and logarithmic equations, and much more, all through exploring real-world scenarios.

Why Take This Course?

In this course, you will learn...

  • To translate word problems into mathematical expressions or equations
  • To manipulate algebraic expressions and solve equations
  • To graph different types of functions and to understand the relationship between a function’s graph and its equation
  • To model growth and decay

Prerequisites and Requirements

Basic arithmetic - addition, subtraction, multiplication and division of positive and negative numbers.

See the Technology Requirements for using Udacity.
