Prealgebra and Introductory Algebra is an answer to the cry for a combined book for the first two courses in developmental mathematics. Taking advantage of a traditional approach to the subject matter, this text builds on the quality of examples, exercises, writing style, and accuracy that you've come to expect when you see the Lial name. Using everyday, realistic applications to increase student motivation, the authors answer the question "When am I ever going to use this?" The worktext format encourages students to become actively involved in their learning. The end of chapter material helps students focus on what is important and solidify what they have learned.
