A traditional coverage of Beginning and Intermediate Algebra, covering linear equations, graphing, inequalities, systems of equations, polynomials, factoring, rationals, radicals, quadratics, and functions.
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.
