In Module 2, Topic A, students look at incidence relationships in networks and encode information about them via high-dimensional matrices. Questions on counting routes, the results of combining networks, payoffs, and other applications, provide context and use for matrix manipulations:  matrix addition and subtraction, matrix product, and multiplication of matrices by scalars.

Note: Although this module is identified as Precalculus and Advanced Topics in the EngageNY curriculum, it corresponds to the Algebra II and Algebra II with Trigonometry Alabama Courses of Study.
