• The estimation coverage develops the ability to make quick, informed decisions in various contexts. A new estimation and graphs section helps build this crucial skill.

• The Math of Finance chapter increases the emphasis on technology tools for investments and loans to help students learn financial skills and make informed fiscal decisions.

• The redesigned Statistics chapter develops statistical thinking skills with new coverage throughout, including a new section on gathering, organizing and displaying data.

• Application Examples, Exercises and Excursions have been updated to reflect recent data and developments with engaging applications such as coffee houses, QR codes and more.

• The Excursion at the end of every section enables students to take an active role in the learning process with engaging applications such as tessellations in Section 7.3.

• At various places throughout the text, a thought-provoking question is posed to encourage students to pause, think about the current discussion and answer the question.

• Learning support includes worked examples, Check Your Progress sections, Chapter Summaries, special notes, videos and a wide range of exercise types.

• Extension Exercises at the end of each exercise set extend the concepts. These are typically more challenging and require more time and effort than the preceding exercises.

Cengage provides a range of supplements that are updated in coordination with the main title selection. For more information about these supplements, contact your Learning Consultant.
