Ch 9: CEOE Advanced Math: Rational & Irrational Numbers

About This Chapter

Rational numbers are able to be manipulated through traditional mathematical means, while irrational numbers have their own rules. Use this chapter of the CEOE Advanced Math guide to review the differences as you prepare for the certification exam.

CEOE Advanced Math: Rational & Irrational Numbers - Chapter Summary

Irrational numbers have specific expressions for their representations as numerical values, separate from rational numbers. This set of video lessons in the CEOE Advanced Math course gives examples of both to provide you with a comprehensive study session as you approach the day of your certification exam. The topics covered in this chapter are as follows:

  • Examples of rational and irrational numbers
  • Comparing and ordering
  • Graphing on a number line
  • Absolute values
  • Addition and subtraction
  • Multiplication and division
  • Notation for fractions and decimals

These lessons all include a timeline feature located beneath the video, which highlights key areas of the presentation that you can jump to with ease. You can also take the collection of self-assessment quizzes we have provided so that you can see how much more studying you should do before the day of your CEOE Advanced Math exam comes.
