GED Basics: 2026 Math Test Overview

A brief(ish) introduction to the GED Math test: what's on it? What's not on it? How should you study? Includes one typical GED-style question at the end. Here are the subtopics mentioned in the video: --BASIC MATH-- * Whole numbers, fractions, and decimals * Squares, square roots, cubes, and cube roots of numbers * Exponents! * "Undefined" expressions (i.e., denominators are 0) * Distance between numbers on a number line using absolute value * Unit rates (e.g. miles per hour, dollars per pound) * Ratios, proportions, and percents * Least common multiple, greatest common factor --GEOMETRY-- * Area & perimeter of two-dimensional shapes * Side lengths of triangles, rectangles, etc (when given the area or perimeter) * Area & circumference of a circle * Bar graphs, circle graphs, dot plots, histograms, etc. * Volume and surface area of three dimensional shapes (find missing side lengths.) * Mean, median, mode, and range (find a missing value when given an average) * Probability --BASIC ALGEBRA-- * Translate algebraic expressions to English, and vice versa * Linear equations (e.g., y = 2x-1); word problems therewith * Inequalities (e.g., 3 is greater than 2x-1); word problems therewith * Quadratic equations * Add, subtract, multiply, divide, and factor polynomials (e.g. simplify (x - 7)(x + 1); factor 2x² - 5x - 3) --GRAPHS & FUNCTIONS-- * Graph linear equations * Slope of a line (from a graph, equation, or table) * Slope-intercept formula (y = mx + b) * Evaluating a function (when x = 6, what’s y?) * Translate functions between tables, graphs, descriptions, equations * Recognize if a function’s really a function (e.g., on a table or graph, if there are 2 values for x, it’s not)
