About This Chapter

Review types of arithmetic expressions in time for the GED exam's mathematical reasoning exam. Video lessons and quizzes also cover mathematical formulas and the order of operations for solving an equation.

Math Expressions and Formulas - Chapter Summary

Prepare for the GED exam's mathematical reasoning section by learning how to interpret mathematical notation and set up math problems. Lessons in this chapter cover:

  • Uses of parentheses
  • Order of operations
  • Arithmetic expressions
  • Mathematical formulas

Our knowledgeable instructors deliver content in the form of entertaining video lessons that last between five and ten minutes each. If you'd rather access instruction in a written format, there are also transcripts. Both resources include several mnemonic devices, examples and sample problems to help you understand which mathematical formulas to use and when. Moreover, the corresponding multiple-choice quizzes can be used to assess your knowledge of the material before, during and after you've viewed the lessons.

Math Expressions and Formulas - Chapter Objectives

The mathematical reasoning portion of the GED test is comprised of two parts, and you'll be allotted 90 minutes to complete them. Approximately half of the test questions assess your algebraic problem-solving skills, while the other half are designed to test your quantitative problem-solving abilities through a series of matching, multiple-choice, hot spot and fill-in-the-blank question formats.

Topics covered in this chapter are applicable to all math test questions, since you'll need a basic understanding of arithmetic expressions and processes to answer them. Your scores on the mathematical reasoning portion will be combined with your results on the social studies, science and language arts sections to determine whether or not you possess the academic skills equivalent to those of a high school graduate.
