A relevant, refreshing new textbook for the Liberal Arts Math course

Quantitative Literacy:The ability to understand and deal effectively with quantitative issues that people face in their everyday lives.

How do you engage students with the study of math? Crauder, Evans, Johnson, and Noell have found the answer: Help them become intelligent consumers of the quantitative data to which they are exposed every day—in the news, on TV, and on the Internet. In an age of credit card debt, opinion polls, and questionable statistics, too few students have mastered the basic mathematical concepts required to think about and evaluate data. Quantitative Literacy: Thinking Between the Lines develops mathematical ideas such as rate of change as key concepts in helping students make good personal, financial, and political decisions. The goal of Quantitative Literacy is a more informed generation of college students who think critically about the data provided to them, the images shown to them, and the offers made to them. Quantitative Literacy shows students the mathematics that matters to them: their bank account, their medical tests, their daily news feed. It also develops their mathematical thinking, helping them to understand the difference between truthful and misleading mathematical reporting.

Text Features • News Articles – pulled from contemporary sources – are used to introduce topics and provide relevant exercises. • Quick Reviews provide concise instruction and review of basic mathematical operations required to think critically and solve problems. • Key Concepts call attention to important concepts and provide a built-in review of each section and chapter. • OptionalAlgebraic Spotlights provide explanations of the mathematical reasoning underlying core mathematical formulas. • Single-stepWorked Examples in each section focus on key concepts, providing a foundation for multi-step Worked Examples.

It’s All in the ExamplesAfter taking your course and working with Quantitative Literacy, students will be equipped to think about and answer all of the following questions: • WilltheAtkinsDietreallyhelpmeloseweight? • HowdoIuselogictogetthebestresultsfromaGooglesearch? • Howdoesthelocalcarpetstoretrytofoolmeintothinkingtheir prices are lower because they quote price by the square foot instead of the square yard? • HowfarcanIgoonthistankofgas? • HowdoIinterprettheresultsofmymedicaltests? • Howcanbusinesspeopleandpoliticiansusegraphsandcharts to mislead me? • WillinflationaffectmysavingsandtheageatwhichIcanretire? • HowdoIavoidgettingtrickedbyaPonzischeme? • Iwanttobuyanewcarintwoyears.HowmuchdoIneedtosave each month to achieve my goal?
