Tussy/Gustafson's ELEMENTARY AND INTERMEDIATE ALGEBRA, 6th Edition, eases teaching challenges while meeting the educational needs of a new generation. The uniquely modern, balanced approach, integrates conceptual understanding with traditional skill and practice that is reinforced through an interactive digital experience in WebAssign. Students gain a deeper understanding if they know why a particular problem-solving approach was taken. Each worked example in the text includes a Strategy and Why explanation, providing students with a concise “why” to equip them to succeed at the “how.” Algebra is not just about the x -- it's also about the WHY. When the algebraic topics studied are put to use, it leads to increased credibility. A large number of real-life applications are included that will help you answer that often-posed question from your students, “when will I ever use this?”
