Finite Mathematics, 11th edition

About the Textbook

• A wide variety of applications reference real data from articles in newspapers, journals, and websites. Examples and exercises with recent data help students learn how the mathematics is applied to their field of study, immediately addressing the question, “Why are we learning this?” NEW! The authors have added or updated 107 (12.5%) of the application exercises throughout the text.
• Apply It opens most sections with a provocative, real-world oriented question that is addressed in the exposition and exercises.
• Applied exercises are grouped by type of application and highlighted for easy identification.
• Extended Applications appear at the end of all chapters to stimulate student interest and foster in-depth learning. Directions for Group Projects in the Extended Applications provide an opportunity for cooperative learning.
• Index of Applications provides instructors and students with an overview of the types of applications throughout the book.
• Application exercises within MyMathLab are labeled by type of application.
• Assessment and remediation features appear at key points to ensure that students keep up with the material, and provide plenty of pointers to help those who fall behind.
•  “Your Turn” exercises following selected examples provide students with an easy way to stop and check their understanding of the skill or concept being presented. Answers are provided at the end of the section’s exercises.
• NEW! Warm-Up exercises were added to many exercise sets to provide an opportunity for students to refresh key prerequisite skills at “point of use.” Each exercise includes a note about where students can go for help if needed.
• The Prerequisite Skills Diagnostic Test, just prior to Chapter R, gives students and instructors an opportunity to assess students’ skills on topics that are critical to success in this course. Answers refer to specific review material in the text for targeted remediation.
• An Algebra Reference chapter appears at the beginning of the text, allowing students to brush up on their algebra skills.
• “For Review” boxes in the margin provide immediate review, or refer students back to appropriate sections as needed.
• “Help text” annotations, set in small blue type, appear next to the steps within worked-out examples and provide an additional aid for students with weaker algebra skills. Many more have been added in this edition.
• Chapter Summaries include important concepts, rules, and formulas, helping students review what they have learned.
• Caution notes warn students of common errors/misconceptions and Note boxes offer additional useful information. Both are highlighted for easy reference.
• Diverse exercise sets show how math is used in students’ major courses of study—business, life science, and social sciences.
• Connection Exercises integrate topics/concepts from different sections. These are denoted with an icon.
• Technology Exercises explore concepts using a graphing calculator or spreadsheet. These are denoted with an icon.
• Concept Check exercises in the Chapter Reviews help students verify their understanding of important topics.
• Reference Tables for Exercises appear in the back of the book. These tables correlate homework exercises to a helpful example in the text.
• Technology coverage keeps your classroom and students up-to-date with the latest software and technology options available on the market.
• The design makes it easy to identify technology coverage so instructors can more easily highlight (or skip) the material.
• Excel^® Spreadsheets are included in examples and exercises where appropriate, allowing students to work problems that closely relate to real-life and business situations.
• Graphing Calculator discussions are included in many examples, but are not essential for understanding the text. NEW! Graphing calculator screens have been updated to reflect the TI-84 Plus C, which features a higher-resolution color screen.
• Technology Notes Material on graphing calculators or Microsoft Excel is clearly labeled to make it easier for instructors to use this material (or not).

MyMathLab is the online homework, tutorial, and assessment program designed for this text to engage students and improve results. Within its structured environment, students learn, practice and apply what they learn, test their understanding, and take advantage of a personalized study plan that adapts to their needs.

• The MyMathLab^® course for this text contains 3,600 assignable exercises with help features that can be customized to the needs of your students. NEW! At the request of MyMathLab users, we added more applications to this revision.
• NEW! Setup & Solve exercises require students to specify how to set up a problem, then solve it. These exercises better mirror what students will be asked to do on tests.
• Application labels within exercise sets (e.g., “Business/Econ”) make it easy for instructors to find types of applications appropriate to students.
• NEW! An Integrated Review version of the course contains pre-assigned diagnostic and remediation resources for key prerequisite skills. Skills Check Quizzes help diagnose gaps in skills prior to each chapter. MyMathLab then provides personalized help on only those skills that a student has not mastered.
• Personalized Homework functionality allows instructors to create homework assignments based on the results of student assessments.
• Tutorial videos for every section of the textbook cover important concepts and terms, and are easily accessible for students who miss lecture. NEW! Videos are available as full-length lectures and as shorter, assignable video clips that focus on a specific concept or example.
• NEW! A Guide to Video-Based Assignments shows which exercises correspond to each video clip, making it easy to assess students after they watch an instructional video. This is perfect for flipped-classroom situations.
• NEW! Tutorial videos involving graphing calculators are now included within MyMathLab exercises to augment videos showing "by hand" methods. If you require graphing calculator usage for the course, your students will find the instruction in these videos very helpful. (If you do not use calculators, you can hide these videos from students.) The videos were created by veteran math instructors at the University of Arkansas with technical assistance from the university's Global Campus.
• NEW! Learning Catalytics is a “bring your own device” student engagement, assessment, and classroom intelligence system. Students use any modern web-enabled device they already have—laptop, smartphone, or tablet. With Learning Catalytics, you assess students in real time, using open-ended tasks to probe student understanding. It allows you to engage students by creating open-ended questions that ask for numerical, algebraic, textual, or graphical responses—or just plain multiple-choice. Students who have access to MyMathLab have instant access to Learning Catalytics and can log in using their MyMathLab username and password. Learning Catalytics contains Pearson-created content for finite mathematics that allows you to take advantage of this exciting technology immediately.

• Warm-Up exercises were added to many exercise sets to provide an opportunity for students to refresh key prerequisite skills at “point of use.”
• Graphing calculator screens have been updated to reflect the TI-84 Plus C, which features color and a much higher resolution screen. Additionally, the graphing calculator notes have been updated throughout.
• More help text in the examples provide an additional aid for students with weaker algebra skills. These notes are set in small blue type next to the steps within worked-out examples.
