These short video lessons on linear algebra will help you get ready for your CEOE Math test. They were developed to assist you in answering test questions about:

  • Using a matrix
  • Performing matrix row operations
  • Explaining matrix notation, equal matrices and math operations with the matrix
  • Working with multiplicative inverses of matrices and matrix equations
  • Solving inverse matrices
  • Finding a determinant of a matrix

Our instructors have kept the videos lessons down to 5-10 minutes each. Each lesson is focused on a specific aspect of matrices in linear algebra, and each ends with a quiz to check to see if you got what was in the lesson. If you need to, you can refer back using the lesson transcript or use the timeline tool provided to go directly to the place in the video that covers whatever you want to review. We also include a feature that allows you to submit a question to our experts.
