(10) Graph theory - the degree of a vertex in a graph, the adjacency matrix A of a graph, the meaning of the entries in A*
(11) Graph theory - the meaning of the entries in BBT and BTB, where B is the vertex-edge incidence matrix of the graph.
(12) Discrete Dynamical Systems (like the Owls and Seals problems), the "Leslie Matrix", or "transition matrix"
