This one teaches students how to think.Dr. Timothy Chae is a former university professor and Math and Statistics specialist who reveals a proven method for raising standardized test scores without endless memorization or gimmicks.After decades of teaching and research, Dr. Chae uncovered the real reason even straight A students underperform on exams like the ACT, SAT, PSAT, GRE, and GMAT. The problem is not intelligence. It is how math is learned and how test thinking is trained.Dr. Chae has coached AMC competition students and served as a statistical consultant for U.S. Department of Education funded research projects. His ACT Math series is built on solid research, real classroom results, and over 20 years of university level teaching experience.This book does not rely on tricks that stop working under pressure. It builds the exact skills the ACT actually tests:Critical reasoning and logical thinkingStrong foundations in algebra and geometryData analysis and mathematical modelingSpeed, accuracy, and confidence under time pressureParents and students choose this series because it produces real, lasting improvement, not short term score bumps.Inside this book, you will find:High impact ACT question types that appear again and againStep by step methods that eliminate careless mistakesA structured practice system that builds mastery fastClear thinking frameworks that transfer beyond the ACTIf you are serious about raising your ACT Math score and building real math power that lasts beyond test day, this book was written for you.- Table of Contents -Chapter 1 Introduction: Overview of the ACTComparison of the ACT and SATACT Math Content and WeightChapter 2 Pre-AlgebraLearning ObjectivesWhole Numbers and IntegersFraction OperationsRatios and ProportionsAbsolute ValueExponents and RadicalsEstimation and RoundingPre-Algebra EXERCISESPre-Algebra EXPLANATIONS, ANSWERSChapter 3 Elementary AlgebraLearning ObjectivesLinear EquationsInequalitiesAbsolute Value EquationsFactoringWord Problems: Step-by-Step StrategyElementary Algebra EXERCISESChapter 4 Intermediate AlgebraLearning ObjectivesQuadratic EquationsPolynomialsRational ExpressionsSystems of EquationsFunctionsComplex NumbersLogarithmsSequences and Number SeriesUnit ConversionsMatricesIntermediate Algebra EXERCISESChapter 5 Coordinate GeometryLearning ObjectivesGraphing Lines and ParabolasDistance between Two PointsMidpoint of a SegmentCircle EquationsConic SectionsCoordinate Geometry EXERCISESChapter 6 Plane Geometry, TrigonometryLearning ObjectivesTriangle AreaPythagorean TheoremRectangle Area and PerimeterCircle Area and CircumferenceVolume and Surface Area of 3D ShapesTrigonometric RatiosUnit CircleGraphs of Basic Trigonometric FunctionsStandard Forms of Trigonometric FunctionsTrigonometric IdentitiesPlane Geometry, Trigonometry EXERCISESChapter 7 Statistics & ProbabilityLearning ObjectivesMean, Median, ModeStandard DeviationData InterpretationProbabilityPermutations and CombinationsStatistics, Probability EXERCISESChapter 8 Four ACT Practice TestsCategory and Difficulty ClassificationPractice Test, Answers and ExplanationsACT Score Conversion Table", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/824/462/9798244628838_b.jpg", "price_data" : { "retail_price" : "26.99", "online_price" : "26.99", "our_price" : "26.99", "club_price" : "26.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
