Full Description
Written for the Math for Liberal Arts course, "Topics in Contemporary Mathematics" helps students see math at work in the world by presenting problem solving in purposeful and meaningful contexts. Many of the problems in the text demonstrate how math relates to subjects - such as sociology, psychology, business, and technology - that generally interest students.
