- More than 5000 end-of-section exercises

## The zyBooks Approach

### Less text doesn’t mean less learning.

This product provides a highly engaging, interactive approach to learning precalculus topics. Concepts are taught not just through text and figures, but also through animations and learning questions. Animations help students visualize and understand key concepts. Learning questions engage students, walking them through concepts step-by-step, with thorough explanations of not only right answers, but also of wrong answers (thus helping to break down common student misconceptions, which is needed to enable learning). A key benefit of interactivity is that students learn more and come to lecture more engaged when points are given for completing the activities beforehand. A “zyEdition” like this one adds interactive items to a base textbook, in this case to OpenStax’s Precalculus. This zyEdition can also be mix-and-matched with other zyBook products, such as Algebra or Calculus.
