Elementary algebra, also known as college algebra, encompasses the basic concepts of algebra. It is often contrasted with arithmetic: arithmetic deals with specified numbers, whilst algebra introduces variables (quantities without fixed values).
This textbook, Elementary Algebra, is the first part, written in a clear and concise manner, making no assumption of prior algebra experience. It carefully guides students from the basics to the more advanced techniques required to be successful in the next course.
Introduction; 2.1 Solve Equations Using the Subtraction and Addition Properties of Equality; 2.2 Solve Equations using the Division and Multiplication Properties of Equality; 2.3 Solve Equations with Variables and Constants on Both Sides; 2.4 Use a General Strategy to Solve Linear Equations; 2.5 Solve Equations with Fractions or Decimals; 2.6 Solve a Formula for a Specific Variable
Elementary algebra, branch of mathematics that deals with the general properties of numbers and the relations between them. Algebra is fundamental not only to all further mathematics and statistics but to the natural sciences, computer science, economics, and business.
The Algebra 1 course, often taught in the 9th grade, covers Linear equations, inequalities, functions, and graphs; Systems of equations and inequalities; Extension of the concept of a function; Exponential models; and Quadratic equations, functions, and graphs.

Feb 22, 2022 · The book covers all the concepts expected to be covered in Elementary algebra. The table of contents is organized and easy to use to navigate between the topics. The index used at the end provides a quick way to review formulas using the links provided.
Be Prepared 1.8. A more thorough introduction to the topics covered in this section can be found in the Prealgebra chapters, Decimals and Properties of Real Numbers. Simplify Expressions with Square Roots. Remember that when a number n is multiplied by itself, we write n2 n 2 and read it “n squared.” The result is called the square of n.
