## Overview

Kaseberg/Cripe/Wildman's respected INTRODUCTORY ALGEBRA is known for an informal, interactive style that makes algebra more accessible to students while maintaining a high level of mathematical accuracy. This new edition introduces two new co-authors, Greg Cripe and Peter Wildman. The three authors have created a new textbook that introduces new pedagogy to teach students how to be better prepared to succeed in math and then life by strengthening their ability to solve critical-thinking problems. This text's popularity is attributable to the author's use of guided discovery, explorations, and problem solving, all of which help students learn new concepts and strengthen their skill retention.

- In order to preserve alignment of the content with the AMATYC standards but also to reflect the evolution of these standards over the years, content has been rethought and rearranged to focus on linear functions.
- Practice problems have been added throughout the text, usually following key Examples, giving students an opportunity to practice the concept demonstrated in the preceding Example. Clear explanations and accompanying practice problems are integrated throughout and serve to reinforce concept comprehension. Answers to the Practice problems appear in the Answer Boxes at the end of the section.
- Reading Questions, which appear after the Answer Boxes, encourage students to examine the nuances of the vocabulary and to recognize that the language of algebra and its vocabulary is an essential part of comprehension. As a result, students are encouraged to discuss their results with classmates when they return to the next class. Answers to the Reading Questions can be found in the Annotated Instructor's Edition only.
- Activities, located at the end of each section, provide opportunities for students to do meaningful and interactive mathematics during class. The activities are paired or group exercises meant for exploration, summation, or extension of basic ideas. In many sections, the Activity reflects how the mathematics applies to things of interest to the student.
- Projects, located at the end of the Exercises, can serve as another opportunity for in-class activities or can be assigned as homework. All have been thoroughly evaluated, some revised, and others added as brand new.
- The number of word problems and applications has been increased to replace some of the skill problems.
- Exclusively from Cengage Learning, Enhanced WebAssign® combines the exceptional Mathematics content that you know and love with the most powerful online homework solution, WebAssign®. Enhanced WebAssign® engages students with immediate feedback, rich tutorial content, and interactive eBooks helping students to develop a deeper conceptual understanding of their subject matter. Online assignments can be built by selecting from thousands of text-specific problems or supplemented with problems from any Cengage Learning textbook.
- A chapter on Statistics, Chapter 10, has been added and is available online.
- In Chapter 2, the more familiar exponent and order of operations topics are now placed before number properties.
- In Chapter 3, solving equations with tables and graphs is now before solving with algebraic notation.
- Solving formulas has been moved from Chapter 4 to Chapter 3
- Chapters 4 and 5 have been exchanged, placing Ratios, Rates, and Proportional Reasoning before Functions, Linear Equations, and Linear Inequalities.
- Percents and Right Triangle Trigonometry have been given individual sections in Chapter 4.
- Averages, formerly with ratios and rates material, are now in Chapter 10, "Statistics."
- Range, Box and Whisker Plot, and Standard Deviation moved from square root (Chapter 8) to an online chapter, Chapter 10, "Statistics."

- A list of Objectives is included at the beginning of the section. They serve as a summary for both students and instructors and coordinate with the titles of the Examples.
- The Warm-Up at the beginning of each section is designed to serve as a class opener, reviewing important concepts, beginning exploration, and linking prior and upcoming topics. Warm-Ups tend to be skill-oriented; they generally connect to the algebra needed to solve text examples. The answers to the Warm-Up appear in the Answer Box at the end of the section.
- Each Example begins with a title, which states the purpose of the Example. Usually these titles relate back to the objectives for the section. Several Examples link with others elsewhere in the book.
- Included throughout the text, Explorations are another type of Example that is intended to be used in class for individual or group exploration.
- Answers to the Warm-Up and some Examples, as well as the Practice questions, are placed in the Answer Box at the end of each section. By providing answers as feedback, the Answer Box permits the text to be used in class or as a laboratory manual for group work or independent study.
- Exercises include questions on problem solving and Projects that relate to topics from prior chapters.
- Instructor Extras are available in the Annotated Instructor's Edition in the margin next to examples. These additional examples can be written on the board for student groups, presented in class, or used as quiz or test questions.
- A graphing calculator continues to be incorporated where appropriate, including the addition of more screenshots, and an appendix has been crafted to further support the natural integration of the calculator in the text.
- Chapter Projects, included the Chapter Review Exercises at the end of each chapter, synthesize multiple concepts and teach problem-solving skills.
- Every chapter ends with a Chapter Summary, Review Exercises, and a Chapter Test in order to review the Objectives presented in each chapter.
