Mental Math boxes ask students to employ analytical skills and solve problems intuitively and without a pencil. They can be used as inclass oral exercises or as preludes to exercise sets. Conceptual Exercises, identified by an icon, are written to help students asses their understanding of concepts in a section.
Practice Problems are found in the margins next to examples  this allows students to check their understanding of a concept before continuing. Cumulative Reviews in every chapter include worked examples from previous chapters. Students can find the answers in an appendix, as well as a reference to where the problem first appeared so that a complete solution is available to them if needed.
Problem Solving exercises are featured throughout and are highlighted in exercise sets. Geometry concepts and applications are incorporated where appropriate. NEW—Emphasis on analyzing data has been increased. Bar graphs, circle graphs, and real data are included where applicable to emphasize the (sometimes visual) connection between data analysis and math.
NEW—Skills Practice applied exercises throughout help mathematically challenged students make connections between math, other courses and the real world. NEW—Unique chapter openers feature vignettes and related photographs demonstrating reallife applications of mathematics. Vignettes are summarized at ends of chapters with boxes stressing problem solving critical thinking skills, and group activities.
NEW—Definitions are clearly explained, both visually (definitions are summarized and highlighted by color) and by worked example. Ideal for visual learners, and/or for those who learn best by example. (NOTE: Each chapter ends with highlights, review, test and cumulative review.)
