#### The zyBooks Approach

Provides an exceptionally-interactive introduction to algebra, with hundreds of embedded learning questions, animations, and built-in, auto-generated/auto-graded challenge activities. Animations make challenging concepts clear, learning questions engage students, and challenge activities allow practice and demonstration of skill. This zyBook is well suited for a first course in college algebra, and serves as a replacement for a traditional textbook and homework system.

The challenge activities include homework-appropriate challenges like simplifying expressions using the laws of exponents, polynomial division, dividing rational expressions, etc. The zyBook integrates the challenge activities throughout the learning content, so that students learn both theory and practice. The challenge activities provide a form of adaptivity, initially presenting basic problem versions, and building to harder problems as the student correctly solves problems.
