Elayn Martin-Gay believes every student can succeed and that is the motivating force behind her best-selling texts and acclaimed video program. With Martin-Gay you get 100% consistency in voice from text to video! Prealgebra and Introductory Algebra 2e is appropriate for a 2-sem sequence of Prealgebra (Basic Math with very early introduction to algebra) and Introductory Algebra (aka Elementary Algebra). This text was written to help students effectively make the transition from arithmetic to algebra and provide a strong foundation for success in their next, intermediate algebra course. To reach this goal, Martin-Gay introduces algebraic concepts early and repeats them as she treats traditional arithmetic topics, and then further develops their exposure to elementary-level algebra topics. The material from this text is also available split out into two separate textbooks, Prealgebra 5e and Introductory Algebra 3e, if you prefer to use split textbooks, rather than one combined textbook for your 2-sem sequence.
