## MTEL Middle School Math/Science: Matrices in Linear Algebra - Chapter Summary

Prior to taking the exam, use these lesson videos to review the steps used to write systems of equations in a matrix form. You may also explore the different operations you can complete within the matrix. Each lesson is taught by an expert instructor who will walk you through example problems and explain:

• How to write linear systems in matrix form
• Performing matrix operations and determining if two matrices are alike
• Completing matrix row operations
• Uses and operations for finding inverse matrices
• Gaussian elimination and solving linear systems
• Purpose of Cramer's Rule with inconsistent and dependent systems
• Finding the determinant of a matrix

After completing a lesson, take the quiz that accompanies it to test your retention of the material. Once you get your quiz results, review them so that you can improve your understanding of the above concepts. If you find any topics that you are unable to master, use the teacher tab of the lessons to get assistance from our instructors.

### MTEL Middle School Math/Science: Matrices in Linear Algebra Objectives

The Massachusetts Tests for Educator Licensure (MTEL): Mathematics/Science (Middle School) exam is a four-hour exam used to measure the mathematical and scientific competencies of future middle-grades math and science teachers in the state of Massachusetts. To complete its objective, this computer-based exam asks test takers to complete 100 multiple-choice questions and two open-response assignments. Of the material that your score will be based on, 5% is about trigonometry, calculus and discrete mathematics. This chapter will help you prepare for some of these questions by improving your understanding of matrices the operations of matrices.
