Ch 21: PSAT Math: Inequalities

About This Chapter

Review the elements of math inequalities to prepare for the PSAT. Video lessons and quizzes incorporate all of the elements of the math inequalities section in a simple and clear manner.

PSAT Math: Inequalities - Chapter Summary

Follow these math inequality concepts to assist you in garnering high scores when taking the math section of the PSAT. These video lessons can help train you in:

  • Identifying inequalities
  • Solving and graphing absolute value inequalities
  • Setting notation, compound inequalities and system inequalities

This chapter provides you with short, easy-to-understand video lessons. After watching the video lessons, you'll find quizzes that provide you with feedback immediately after completion. Use this feedback to decide if you're prepared to take the PSAT math test.

PSAT Math Objectives

The PSAT math portion consists of 40 multiple-choice questions and eight student-produced response questions, or grid-ins across two sections. While taking the PSAT math test, you're allowed to use a calculator to assist with answering questions in one section, but there is a section where use of a calculator is prohibited. Below are the three areas of emphasis that are covered in the PSAT math test:

  • Heart of Algebra
  • Problem solving and data analysis
  • Passport to Advanced Matrh

The PSAT's goal is to help you assess whether or not you're ready to take the SAT, as well as give you an idea of what you can expect the SATs to look like. PSAT results explain your strengths and weaknesses, which you may want to improve. Since the PSAT is co-sponsored by the National Merit Scholarship Corporation (NMSC), you're able to access tools for career and college planning. You may also be selected to participate in an NMSC scholarship program.
