Networks and Matricies

Today in class Mr.Max taught us all about Networks and Matricies. There are 2 ways of doing this: Directed(One Way) .Vs. Non-Directed(2-Ways). There are Nodes/ Vertex Points (Verticies) connected by Routes/Edges. He also taught us how to enter the info onto our calculator. He made us take the networks and make them into matricies which took a long time. A direct route matrix goes from start_?_ finish. A non- direct route goes from start_?_finish or start_?_ _?_finish. He finished the class of by Assignin us practise questions that have to do with Networks and Matricies.
