GED® Math Review: Algebra, Functions and Data (Volume 2)
A thorough GED® Mathematical Reasoning review of the algebraic and statistical half of the test: algebraic expressions, linear equations and inequalities, systems of equations, quadratic equations, functions and graphs, coordinate geometry (slope, intercepts, parallel and perpendicular lines), data analysis (mean, median, mode, range, IQR, box plots), probability, counting principles, and advanced geometry (angle relationships, similar figures, special right triangles). The 46-question MCQ set spans all difficulty levels with full explanations.
