I had difficulty finding a single, concise treatment online of the construction of numbers from the naturals through the reals. I have collected my notes in a document (<1,200 words) and before I present them as the concise introduction I had been looking for, I want feedback so I may correct any errors in my understanding or its expression.
My hunch is that this topic would not be appropriate for a math.stackexchange.com question. In the judgment of community participants, is that accurate? If so, where online might be an appropriate place to offer access to the document and invite feedback?
