How should you answer questions to puzzles when you have multiple guesses/iterations of your thoughts for answering a puzzle? 

For example: [This puzzle]( I have 3 distinct guesses which happen to be iterations of each other, but could stand alone.

[This answer]( was the 3rd answer from the user where he explored different methods to coming up with a proof.

In short (TLDR;): should each puzzle be 1 answer per user or is there some threshold for each answer being put into separate answers? 

**Edit**: Just found [the meta post]( on the subject, but it might be good to figure out how it applies to this site.
