A graph can be represented by an adjacency matrix but how is that a real mathematical matrix and not just a table?(adsbygoogle = window.adsbygoogle || []).push({});

A matrix is part of an equation system Ax=B but what is x and B in this case if A is the adjacency matrix?

For example Google does PageRank with Eigenvalues but what would different operations on an adjacency matrix mean, why is it valid to compute eigenvalues and eigenvectors on an adjacency matrix?

Like taking the determinant of an adjacency matrix, what information do we get?
