I have a question about my Mathematics Stack Exchange post: Meaning of “modulo the identity matrix”
- Sorry if this is the wrong place for these Qs; I'm new to math.stackexchange and I don't know where to ask these Qs. If this is the wrong place, where should I ask Qs like these?
- I posted a Q about 𝑃𝑆𝐿(2,𝑅) Oct. 22. Three comments and 1 answer were posted in response. How do I respond to a specific comment and how do I respond to an answer?
- I got the idea that I should respond to an answer by editing my original Q. Is that right?
- If I edit my original Q, say, a month or two later, how will anyone see my edits so they might respond to my edits? Thanks.
