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.
