Episode 14d (8:03):
The Big Picture for the four basic kinds of Reduced Row Echelon Form, $\mathbf{R}_{\mathbf{A}}$

Summary:

We present a table of the four forms of Reduced Row Echelon Form, $\mathbf{R}_{\mathbf{A}}$, showing how each shape leads to a distinct kind of Big Picture. We include the number of possible solutions to $\mathbf{A}\vec{x} = \vec{b}$ and how these connect to the $\mathbf{A}$'s Right and Left Nullspaces.
