Amusingly, I discovered a method very similar to this in college. My method was simpler - stick a 1 in front of one chemical, then you get an n x n linear system of equations for the remaining compounds. Solve it, then figure out what to multiply by to get an int solution. I suspect that my version isn&#x27;t stable, which I gather is the problem these guys are solving.<p>I was forbidden from using this method on the final, since it isn&#x27;t the ad-hoc method that was taught.
