Peterson's, Aug 1, 2010 - Study Aids
Peterson's Master the GED: Math Review: Algebra and Descriptive Statistics offers readers an in-depth review of algebra and descriptive statistics for the GED Mathematics Test, Parts I and II. Readers who need additional practice for the Mathematics Test, will benefit greatly from the lessons and practice questions on:
• Linear equations in one variable
• Linear equations in two variables
• Linear equations that can't be solved
• Solving algebraic inequalities
• Factorable quadratic expressions (one variable)
• Factorable quadratic expressions (two variables)
• Functions
• Measures of central tendency (mean, median, and range)
• Arithmetic series
• Probability
• Word problems involving formulas
Looking for extra algebra help? Throughout this review, you'll see easy-to-use links to HippoCampus.org, an innovative Web site where you will find interactive subject help via high-quality multimedia lessons and course content.
