Matrices and Vectors - Algebra 2 - Chapter 12

Section 3.6 and Chapter 12 of the eText Algebra 2 book on your laptops introduce the topics of matrices and vectors.  If you plan on pursuing an engineering degree or computer science degree, I would suggest exploring the concepts of matrices and vectors prior to entering college.
