GED 2027 Mathematical Reasoning

Revised and updated for 2027. Most GED math books throw hundreds of questions at you and hope something sticks. This one actually teaches you the math first.

New for 2027: fresh practice test questions, a guide to testing online or at a test center, the correct calculator rules, a Most-Missed Skills checklist, and answer keys checked again by an expert.

Every chapter starts by explaining the concept from scratch — what it is, why it matters, and how it works — using plain language and real-world examples like budgeting, shopping, cooking, and driving. Then you see it solved step by step in a worked example. Then you try it yourself with guided practice. Only after you truly understand does the chapter move to test-style questions. This is a study guide that teaches, not just a question bank that tests.

Covers every topic on the GED Mathematical Reasoning exam: number sense, fractions, decimals, percents, ratios, algebra, geometry, data analysis, and word problems. Each concept builds on the last, so you're never lost. "Common Mistake" callouts warn you about traps before you fall into them. "Test Tip" boxes give you practical strategies for test day. "Try It" sections let you practice immediately — with detailed answer explanations that show exactly why each answer is right and why each wrong answer is wrong.

Built for adult learners and ESL students who haven't touched math in years. Includes the complete GED formula sheet with plain-English explanations, TI-30XS calculator tips, and two full-length practice tests. Whether you're starting from zero or brushing up, this book meets you where you are.
