GED® Math: Algebra In Depth
A complete, step-by-step algebra course for the GED®. We start from the very meaning of a variable and build carefully through expressions, equations, inequalities, graphing, systems, exponents, polynomials, factoring, quadratics, and functions. Every idea is explained in plain language with multiple worked examples, common-mistake warnings, and visual graphs.
