Paperback. Condición: New. Print on Demand. This book begins by defining what an equation is, and uses simple examples to explain how to solve for an unknown variable. The author walks readers through the process of solving equations more complex than simple one-step equations, and introduces equations with variables on both sides of the "equals" sign. Later chapters consider equations that deal with angles and introduce concepts of negative and positive numbers and how to add and subtract positive and negative numbers. Throughout the book, problems are presented with examples of problems in everyday life that can be solved with the principles of algebra. By the end of the book, the author demonstrates how to solve more complex equations and polynomials, and shows how to check answers.
