##### Description

The Rockswold/Krieger algebra series fosters conceptual understanding by using relevant applications and visualization to show students why math matters. It answers the common question “When will I ever use this?” Rockswold teaches students the math in context, rather than including the applications at the end of the presentation. By seamlessly integrating meaningful applications that include real data and supporting visuals (graphs, tables, charts, colors, and diagrams), students are able to see how math impacts their lives as they learn the concepts. The authors believe this approach deepens conceptual understanding and better prepares students for future math courses and life.

##### New to this edition

New and Updated Features

• Updated data in hundreds of exercises and examples keep the applications relevant and fresh.
• Increased visualization: whenever appropriate, the mathematics have been made more visual by using more graphs, tables, charts, color, and diagrams to explain important concepts with fewer words. Titles and comments have been added to the graphs. Green equation labels have been added to calculator graphs that are written in standard notation.
• New Vocabulary is listed at the start of every section, highlighting the math concepts that are introduced in that section. This gives students a glimpse of the big picture of the section and helps with test preparation.
• Reading Check questions appear alongside important concepts, ensuring that students understand the material they have just read. These are located throughout every section.
• Study Tips appear throughout the text to give not only general study advice but also specific pointers that relate to learning specific mathematical concepts.
• Application Topics: students are more engaged when mathematics is tied to current and relevant topics. Several new examples have been added that discuss the mathematics of the Internet, social networking, tablet computers, and other contemporary topics.
• Online Exploration Exercises throughout the text invite students to use the Internet to explore real-world mathematics.

New Instructor and Student Resources

• Objective-based Worksheetsprovide extra practice for every text section. Designed to be lab- and classroom-friendly, they offer:
• Vocabulary review and practice problems.
• A structured learning process to promote student success.
• Extra practice exercises with ample space for students to show their work.
• Opportunities to explore and compare multiple problem-solving methods through Understanding Concepts through Multiple Approaches.
• Teaching Examples: in the Annotated Instructor’s Edition, every example in the text is now paired with a teaching example that instructors can use in class to promote further understanding.

New to MyMathLab®

New! Two MyMathLab course options are now available: a standard course and a Ready to Go course.

• Standard MyMathLab courses allow instructors to build their course their way, offering maximum flexibility and complete control over all aspects of assignment creation.
• The new Ready to Go courses provide students with all the same great MyMathLab features, but make it easier for instructors to get started. Each course includes pre-assigned homework and quizzes to make creating a course even easier.

Both course options feature the following items:

• Increased exercise coverage provides an assignable MyMathLab problem for almost every problem type from the text
• Pre-made (and pre-assigned in the Ready to Go course) section-level homework assignments.
• Pre-made chapter review quizzes that are pre-assigned in the Ready to Go course and generate personalized homework assignments based on students’ quiz results.
• A Pre-made(and pre-assigned in the Ready to Go Course) pre- and post- test for every chapter.
• Two new types of exercises are now assignable:
• Concept and Vocabulary exercises provide true/false and fill-in-the blank exercises that assess students’ understanding of the definitions and concepts presented in each section.
• Guided Solutions exercises walk students through the steps as they interact with the problem, helping them understand the reasoning behind it. Some of these exercises require students to use multiple methods—(algebraic, numerical, graphical, etc.)—to deepen understanding.
• All Lecture Series Videos for every section of the text and Chapter Test Prep Videos are available within MyMathLab.
• Video lectures are correlated directly to the content in each section of the text.
• Material is presented in a format that stresses student interaction, often using examples from the text.
• Video lectures include English captions.
• The Chapter Test Prep Videos let students watch instructors work through step-by-step solutions to all the Chapter Test exercises from the textbook.  Chapter Test Prep videos are also available on YouTube™ (search using author name and book title).

• Chapter 1: New step diagrams were added to provide students with an organized, visual process for finding the greatest common factor and the least common denominator.
• Chapter 2: New tables summarizing words and phrases associated with mathematical symbols are now included to give students at-a-glance references to aid in setting up and solving application problems.
• Chapter 3: At the request of reviewers, exercises that require students to complete tables of values for linear equations in two variables are now given in both vertical and horizontal format. Also, additional exercises asking students to interpret the meaning of the slope and the intercepts in applications modeled by linear equations in two variables are now included.
• Chapter 4: The discussion and visual representations of the types of systems of equations have been moved to the first section of Chapter 4 to give students immediate exposure to the types of systems that they will encounter throughout the chapter.
• Chapter 5: New tables summarizing rules for exponents are now included to give students immediate access to these important concepts.
• Chapter 7: A new visual method for finding the least common denominator for rational expressions has been added to make this important concept more accessible for students.
• Chapter 8: New visuals for several topics, such as functions, evaluating functions, absolute value equations, and absolute value inequalities, have been added. At the request of reviewers, more explanation is now included for finding the domains of functions. Additional opportunities to represent functions symbolically, numerically, graphically, and verbally have also been included.
• Chapter 9: A new subsection in Section 9.2 related to social networks and matrices was added to keep topics current for students.
• Chapter 10: At the request of reviewers, Section 10.1 was split into two sections so that radical expressions and rational exponents can be taught in two different sections. Section 10.1 was reorganized so that the square root and cube root functions can now be taught in Section 10.1 rather than later in the chapter. At the request of reviewers, greater emphasis has been given to converting between radical forms and forms with rational exponents.
• Chapter 11: At the request of reviewers, Sections 11.1 and 11.2 have been reorganized to put topics in better order for student learning. The topic of increasing and decreasing functions is now optional in Section 11.2. In Section 11.5 the visuals for quadratic inequalities have been increased to make this topic more accessible for students.
• Chapter 12: Section 12.2 has a new subsection on percent change and exponential functions. Greater emphasis was given to percentages and how they relate to exponential functions. At the request of reviewers, the topic of paying interest more than once a year was added in Section 12.2.

##### Features & benefits
