## Overview

*For courses in Elementary and Intermediate Algebra*

**Helping Readers Innovatively "Do the Math"**

*The Sullivan Elementary & Intermediate Developmental Math Series***, 4**^{th}** Edition** introduces readers to the logic, precision and rigor of mathematics, while building a foundation for future success.

Known for their hallmark examples that provide extra step-by-step support, the authors have continued their successful text pedagogy and have focused in the revision to translating it to the MyLab™ Math course for a truly dynamic learning and teaching experience. Key revisions to the MyLab Math course include guided “How To” exercises, modeled on the successful Show Case examples and new GeoGebra applet exercises.

The Sullivan team has revised their MyLab Math course to ensure that readers are getting the most of the resources they have at their disposal. For example, they offer an enhanced e-text that allows readers to easily and quickly refer back to a specific page for examples. To encourage readers, the author team developed a MyLab Math that helps them develop good study skills, garner an understanding of the connections between topics, and work smarter in the process.
