The first book of the Mathematics in Action series, Prealgebra Problem Solving, Third Edition, illustrates how mathematics arises naturally from everyday situations through updated and revised real-life activities and the accompanying practice exercises. Along with the activities and the exercises within the text, MathXL^® and MyMathLab^® have been enhanced to create a better overall learning experience for the reader. Technology integrated throughout the text helps readers interpret real-life data algebraically, numerically, symbolically, and graphically. The active style of this book develops readers’ mathematical literacy and builds a solid foundation for future study in mathematics and other disciplines.
