Networks & Matricies

Today we learnt about Directed(one-way streets) and Non-Directed networks(two-way streets). To do so, we started with a diagram that had routes to the nodes. We had to figure out how many ways we could get from one place to the next either directly, or indirectly(through another node). After we did this for a half hour, Mr.Max showed us how to do it easily on the calculator by taking the direct route matrix and squaring it to get to the second matrix that was from one place to another through one other node.
