Beginning and Intermediate Algebra was designed to reduce textbook costs to students while not reducing the quality of materials. This text includes many detailed examples for each section along with several problems for students to practice and master concepts. Complete answers are included for students to check work and receive immediate feedback on their progress. Topics covered include: pre-algebra review, solving linear equations, graphing linear equations, inequalities, systems of linear equations, polynomials, factoring, rational expressions and equations, radicals, quadratics, and functions including exponential, logarithmic and trigonometric. Each lesson also includes a World View Note which describes how the lesson fits into math history and into the world, including China, Russia, Central America, Persia, Ancient Babylon (present day Iraq) and more!
There are spelling errors on almost every page, and usually at least two wrong answers per section. Most of the explanations are lackluster and only appropriate for someone who previously learnt the material and is just looking to revise. The gradual ramping up in difficulty of the practice problems was really the only thing I enjoyed about this. Despite being completely free to download, I just can't recommend this to anyone, as you will end up frustrated either by the explanations or incorrect answers. Get yourself a cheap secondhand textbook instead.
