# Elementary Algebra

Elementary Algebra is designed to meet the scope and sequence requirements of a one-semester elementary algebra course. The bookâ€™s organization makes it easy to adapt to a variety of course syllabi. The text expands on the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics.
