I'm member of this site for almost 3 years, and I cannot understand why this question takes one down vote and 4 close votes. Can someone who can understand the reason for this explain it to me, please. Which rule that I'm not following, or which criteria does that question fail to fill?
I'm guessing because it is long and the poster has been argumentative with people pointing out things in the mathematics that haven't made sense, with interpretations of the wording in the question that are unjustified, etc. This leads to
- It being unclear exactly what is being asked: are they asking about the validity of their math, or about the correctness of their interpretation of the wording in the question?
- It comes across as not being thought through very well. If requests for clarification are blown off as "not being important" or result in drastic changes in the post, it feels capricious and some people will simply downvote to discourage the frustration level associated with the post. (edit: or vote to close. It has really only received one downvote, I don't know that I would read anything into that.)
I hope others will correct me if they think I'm mistaken, but there are two issues:
The scanned image is a bit of a no-no to some users as these links a) aren't searchable and b) often subsequently break, leaving an unintelligible question.
But the main thing I think, is that there are two camps of users:
- Most users (me included) see this as a question and answer site in which people ask and answer questions. Reasonable questions and answers are acceptable, and those which have particularly resonant, lasting importance, will gain particularly high prominence by virtue of receiving a high number of upvotes. Less-useful questions and answers receive less prominence due to not receiving the same number of upvotes - but are still there for those who may want to dig for them.
- The 2nd camp of users choose not to rely upon the upvote/downvote system to curate the content on the site. They proactively curate the content and their vision is more akin to a canonical repository of a single copy of each maths question. Variants, special cases and inquiries into rarely considered details which they only foresee being of relevance to the original poster, are to be removed as they're not up to the high editorial standards they wish to maintain. Some of the users in this camp are among the most generous contributors to the site.
I think most likely that there were some users in the 2nd camp who felt your question did not meet their curation standards.
