### About this unit

"Module 2 extends the concept of matrices introduced in Module 1. Students look at incidence relationships in networks and encode information about them via high-dimensional matrices. Matrix properties are studied as well as the role of the zero and identity matrices. Students then use matrices to study and solve higher order systems of equations. Vectors are introduced, and students study the arithmetic of vectors and vector magnitude. The module ends as students program video games using matrices and vectors."
