Designed to engage the student as an active participant in the classroom, the Mathematics in Action series presents concepts using real-life activities and reinforces those concepts with practice exercises in the text and in MyMathLab(t). The second book of a three-part series, An Introduction to Algebraic, Graphical, and Numerical 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(R) and MyMathLab(t) have been enhanced to create a better overall learning experience for the student. This unique approach helps students increase their knowledge of mathematics, sharpen their problem-solving skills, and raise their overall confidence in their ability to learn. Technology integrated throughout the text helps students interpret real-life data algebraically, numerically, symbolically, and graphically. The active style of this book develops students' mathematical literacy and builds a solid foundation for future study in mathematics and other disciplines.
