Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align ... We'll also look at how to implement row operations (Gaussian elimination). First we ...

But a new proof establishes that, in fact, the right kind of guessing is sometimes the best way to solve systems of linear equations, one of the bedrock calculations in math. As a result, the proof ...
