### Overview

Get the background you need and discover the usefulness of mathematics in analyzing and solving problems with FINITE MATHEMATICS, 8th Edition. The author clearly explains concepts, and the computations demonstrate enough detail to allow you to follow and learn steps in the problem-solving process. Hundreds of examples and exercises, many based on real-world data, illustrate the practical applications of mathematical concepts. The book also includes technology guidelines to help you successfully use graphing calculators and Microsoft® Excel® to solve selected exercises. Available with InfoTrac® Student Collections http://gocengage.com/infotrac.

### Features and Benefits

• Detailed computations enable students to easily follow successive steps in the problem-solving process.
• More than 3,200 exercises and 500 examples offer instructors and students with an abundance of homework and practice problems. Examples and exercises are cross-referenced, identifying for students a corresponding exercise to check their understanding after they read through an example and solution.
• Exercises are graded by level of difficulty: level 1 for routine problems, level 2 for elementary word problems, and level 3 for more thought-provoking problems.
• Discussion questions provide the option of using the graphing calculator or spreadsheet technology to solve the problem. "Explorations" encourage students to think more deeply about mathematical concepts, often providing an opportunity to use the graphing calculator. Many of these exercises may be used for group projects or writing assignments.
• References to technology keep the text current with new applications. "Using Your TI Graphing Calculator" and "Using Excel" boxes walk students through the steps necessary to apply the technology to selected exercises. Additional guidance on how to use the graphing calculator is found in an appendix.
