@TheSimpliFire you should avoid deleting your answers and just vote the question for closure, and let it be deleted that way, assuming the community agrees
2 reasons I say that. First is that theres nothing wrong with your answers, the problem is with the questions. And second is that I really don't want self-deletetion of this nature to become a fad... The line between pruning and self-vandalism is fuzzy, and self-vandalism is probably the single most annoying thing for mods to clean up.
@Shaun that one will stay deleted, I'm afraid. I'm not opposed to the occasional fun question nor the occasional big-list soft-question, but that is just not to the type of question I want representing MSE to the world. It would be a good fit for r/math, probably.
@XanderHenderson Technically, opinion-based or career-advice questions are unambiguously off-topic, and even have a dedicate close-reason. But I personally never vote on them if they seem to be asked in good faith. You won't go wrong if you vote to close them, and you can also consider commenting that they ask somewhere else such as Academia SE or Math Educators SE if it would be on-topic there.
Question asks "what does this definition mean" for something Smarandache invented. I half feel that it might just be driving metrics up at researchgate.net for bogus research , but suspicions aside, the question is unacceptably unfocused: math.stackexchange.com/q/3075446/29335
@JoséCarlosSantos Actually it doesn't. Once it is negative score, it is open for deletion (you can refresh the page to get the option). Unfortunately I don't have any delete-votes right now.
∆ADB Is A right angled triangle where Angle ADB is 90°,EF is perpendicular to AB From any point E on BD.Line AE intersects the circumcircle of ∆ADB at H,HF and DB intersrcts at G.DE=5 ,EG =3 then What's the value of BG?
@XanderHenderson I don't agree with the idea that such a solution needs deletion at all. I've seen lots of answers of the form "this follows from an application of such and such a theorem thusly..." If it had just been the formula with no context, I might have agreed, but the citation makes it a complete and useful answer. it's doesn't even merit a downvote. I think it makes perfect sense for an answer like this to exist with a low, nonnegative score.
@JoséCarlosSantos I don't see how that is a criterion for deletion. Things that qualify as legit answers should stay put, and then the voting can be the measure of how good it is. Of course, I'm assuming all other things are equal.
In fact, it seems to be the only answer that draws attention to the fact it follows from a known formula, one which is useful to know in general. In that respect it has something the other answers do not...
@rschwieb I did not vote to delete the answer, but I did downvote it. The hovertext for the downvote arrow reads "This answer is not useful." I don't find the answer at all useful. "Go look up a formula in a book" is not, as far as I am concerned, useful.
On the other hand, if the answer read "This is a well known formula: [formula]. It can be derived as follows: [two lines of computation]," then I would feel it was useful.
I agree that calling attention to known results can be helpful, but a good answer needs to be more than the correct Google term (though I do think that "Try Googling geometric series" is a good comment.). ;)
