NES Math: Matrix Operations & Determinants Chapter Objectives

Several states require passing the NES Math exam as one of the conditions for certification to teach the subject at the secondary level. The exam's 150 questions are divided into five content domains. Questions on the topics this chapter covers are in the content domain on statistics, probability and discrete mathematics, which makes up 19% of the test's total score.

All questions on the NES Math exam are multiple choice, requiring you to choose the correct answer from several options. The questions on our lesson quizzes are also multiple-choice, so completing the quizzes can help you get familiar with the format you'll encounter on test day. The quizzes also let you test your knowledge and video links make it easy to return to the lesson to review areas about which you're unsure.
