Mathematics

Lial, Greenwell, and Ritchey continue their tradition of integrating relevant, realistic applications with current data sources to provide an application-oriented text for students majoring in business, management, economics, or the life or social sciences. The many opportunities for technology use allow for increased visualization and a better understanding of difficult concepts. In addition to MyMathLab^®, a complete online course solution, a comprehensive series of video lectures is available for this text.

• An Algebra Reference chapter begins the text, allowing students to brush up on their algebra skills.
• Section Opening Questions are thought-provoking questions that are revisited throughout the section, providing helpful context as students read the text.
• A wide variety of Applications reference real data from articles in newspapers, journals, and books. Examples with recent data help students learn how extensively mathematics is applied, how it relates to the world around them, and how they can use it. Applied exercises are grouped by subject 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.
• Diverse Exercise Sets include exercises from Japan's university entrance exam, showing how math is used in a variety of areas around the world. In addition, there are exercises that require writing and conceptualization in order to promote critical thinking, deeper understanding, and integration of concepts and skills. Connection Exercises, denoted with an icon, integrate topics/concepts from different sections. Technology Exercises, denoted with an icon, explore concepts using a graphing calculator or spreadsheet.
• Margin Reviews provide immediate review, or refer students to appropriate review sections as needed.
• Caution boxes warn students of common errors/misconceptions and Note boxes offer additional useful information. Both are highlighted for easy reference.
• Excel^® Spreadsheets are included in examples and exercises where appropriate, allowing students to work problems that closely relate to real-life and business situations.
• Optional Graphing Calculator Integration: graphing calculator discussions and TI-83/84 Plus screens are used in many examples, but are not essential for understanding the text.
• MyMathLab^® provides a complete online course that is customizable by instructors. This Web-based software includes a wide variety of resources from dynamic multimedia to course management tools. With MyMathLab, instructors can help increase student comprehension and success.

• 30% new or updated exercises in each section keep this text fresh and relevant for today’s students.
• New! Concept Check exercises in the Chapter reviews help students verify their understanding of important topics.
• Updated data and applications use real data from current sources.
• Expanded Chapter Summaries now include important concepts, rules, and formulas, helping students review what they have learned.
• New! Actuarial Problems from real actuarial science examinations and study guides require students to connect a variety of topics to successfully solve a problem. These challenging problems help students to creatively apply what they have learned.
• The Chapter on Logic (Ch. 6) has been re-organized to help the material flow better, helping students learn to create logical proofs. Almost all word problems have been changed or updated for this edition.
• Alternative solutions and aids for finding solutions have been incorporated into this edition based on the authors’ own classroom experience and reviewer suggestions. For example, alternative procedures are provided for finding solutions in Finite Mathematics (see the alternative procedure for calculating probabilities of poker hands in Chapter 8 and the alternative method of finding saddle points in Chapter 11).

Marge Lial was always interested in math; it was her favorite subject in the first grade! Marge's intense desire to educate both her students and herself has inspired the writing of numerous best-selling textbooks. Marge, who received Bachelor's and Master's degrees from California State University at Sacramento, is now affiliated with American River College.

Marge is an avid reader and traveler. Her travel experiences often find their way into her books as applications, exercise sets, and feature sets. She is particularly interested in archeology. Trips to various digs and ruin sites have produced some fascinating problems for her textbooks involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.
