With Fezzik on our side as always, we describe how to find the Nullspace of $\mathbf{A}$, $N(\mathbf{A})$. In contrast to Column Space, we will have one true way to find Nullspace. The big deal again: If the Nullspace of $\mathbf{A}$ is a subspace larger than just $\{\vec{0}\}$, $\mathbf{A}\vec{x}=\vec{b}$ will have infinitely many solutions if $\vec{b} \in C(\mathbf{A})$.
