@ParclyTaxel I am not sure (I cannot find any relevant Meta thread either on Meta Stack Exchange or Mathematics Meta), but I think that casting the last close vote to expedite reopening is not considered proper etiquette.
@ParclyTaxel Flagged as "Needs more focus", but I'm not sure whether that helps. I think a closure flag sends a post into the close review queue (provided it's not already there), but it does not count as a close vote? I'll need to check…
I do not agree that this question should be reopened, because it shows lack of effort. Simply googling for "summation notation" already answers your question. — user2182023 mins ago
^ @XanderHenderson: People are reopen-voting it again...
@ParclyTaxel No, I meant the close queue only. Basically, suppose a post is currently open and I flag it for closure. I believe this sends the post into the "Close votes review queue". But I don't think that flagging it increments the number of close votes on the question.
I mean, just because we can have ∞−x = ∞ for any extended real x<∞, does not mean we should mention it in relation to an obviously bogus subtraction of ∞ from ∞.
@vitamind Go with god, my son. The structure of the post (link to a document containing two years of ponderings and musings, the comment "this is mathematically meaningless", etc) does not give me hope that there is a good question in there anywhere.
My oldest goldfish (I never named it) died today, probably a few months older than 4. Unfortunate that it had to be Mother's day as well. It was a big, golden fish that would even hover around pencils if I lowered them into the tank! It used to love going through the large viaducts and would spend long hours chasing the others around. Fishes are beautiful creatures.
Ok, to PSQs we go.
PSQ In the answer, user is wondering, why the downvote?
PSQ IMO saying they used the techniques of another question isn't valid unless they explain what the technique was.
@Peter No, sorry. I'm working with the really big ones C5000+, so I'm struggling to put anything through. All the curves are moving smoothly, but I fear I'm going to be empty-handed for a long time.
We need two more dvs to delete this question. One reopen vote already cast, likely by the answerer, despite the question being a frequently duplicated question on this site.
Hi, @Bill, @OliverDiaz. This chatroom's level of activity seems to have gotten greatest about -6 UTC to -3.5 UTC. Also a bit -10 to -8 UTC. :( I wish it more consistently busy.
@XanderHenderson I know it's definitely been asked many times about a scalar multiplying a vector (1 x n), or (n x 1), or a scalar multiplying an matrix.
@Xander. Thank you for your comment template on the EoQS's. You you know, or does anyone know, how I can "script(?)" the most common links and comment templates I tend to use most often? It requires a bit of time to locate the sources, not so much for one, but cumulatively over the course of a day.
Anyway, just wondering. I should spend a little time searching on meta.se for any tips. I know @user21820 is handy in this manner, and no doubt others as well.
I just wanna speed dial 1 for one comment template, 2, for another.... I can keep order straight! (I'm sure it's nothing that easy :()
@OliverDiaz I'm sorry, it was sort of a run-on thought. I wanted to greet you both, then merely commented that it sometimes now gets slow about the time you both came in. There was no point; if anything, I was glad to see the presence of two users, that's all.
@OliverDiaz Anything else you want to interrogate me about, while we're at it? Should I never greet you when you come into this room? Should I pretend you aren't here?
@amWhy Not really, bit thanks for the quick salutations. My main objective is help close duplicates (specially when a question does no add anything new or of value to something already done).
@OliverDiaz That's great. We appreciate that. Did you find anything approximating Xander's concern above, about multiplying an n-tuple by a scalar? I see a parallel with multiplying a vector by a scalar.
@Xander, to continue on my comments about your question above, please note the question
I am currently learning calculus and am still a little confused as to the difference between vectors and points (which are represented as ordered pairs). I know that vectors are a different type of object given that they have both direction and magnitude, but I don't understand why they are inher...
