I have removed all annotations from my videos that were used to correct errors (YouTube is
getting rid of Annotattions) Any errors in the videos have been corrected in the NOTES.

If you haven't watched Part I of this series, do it now, here: http://bit.ly/2iOkY70

In this video, we extend the method that we used in part I, to the method called Gauss-Jordan
Elimination Method. Basically, we don't stop when we get the triangular matrix. We go on until we
get an augmented diagonal matrix with ones in the diagonal.

If we cannot get an augmented diagonal matrix with ones in the diagonal then we try to get what
we call an Echelon matrix. In this video, I define what an Echelon matrix is and how to determine
if the system has a unique solution, infinite solutions or is inconsistent (no solution).
