This isn't a Python question, it's an algebra one. I don't know what
Z, S, and so on are, but for the most part, the basic rule of solving
equations applies: Do the same thing to both sides and it's still
true. Work on it until you can isolate SN on one side.

I don't know what this bit means, though:

2.32log(Mr-)

Is this a transcription error? You can't subtract nullness from something.
