Welcome to UW-L's College Algebra Site

The UW System Institute for Innovation in Undergraduate Research and Learning (IIURL) has developed this site to share a collection of digital learning objects (LOs). These materials are designed to support the study of College Algebra and is appropriate for use by the following students:
**those preparing for the College Algebra credit by exam**- those currently taking the course Math 150: College Algebra

Algebra is the language of mathematics. Much of the observable world can be characterized as having patterned regularity where a change in one quantity results in changes in other quantities. Through algebra and the use of variables and functions, mathematical models can be built which are essential to personal, scientific, economic, social, medical, artistic, and civic fields of inquiry.

The modules in this site are introduced using Learning Objects. If you are new to this site, we recommend that you visit the *New to this site?* page.

**If you are preparing for the Credit by Exam:**There are many problems available in the various chapters. Each chapter contains a variety of

*topics*and therefore you should consider working through a number of items in each section to ensure you have covered all topics. However, spending too much time on early topics may result in inadequate time available for topics that come later. In other words, you need to self-assess. We recommend that you try a few problems in each section, noting your skills and understanding of the various topics. Once you visit all sections, return and focus on those sections that you have the least confidence.

**If you are enrolled in Math 150:**The materials in this site can be used to supplement the coverage of the topics presented in class. Be aware that different instructors may choose to cover the topics in a different order, and the chapter names/numbers might not match those of your textbook.

In this course you will find digital materials clustered into the following five areas:
