math.stackexchange.com/questions/3052944/weird-elevator-riddle was closed as lacking context but as far as I can see it gives a specific background as to what is being asked and what motivated it.
In fact, the persons says "My apartment has two elevators, and there are 19 floors, from b1 to 18. There are two lift buttons (up and down) on each floor except b1 which only has UP and 18 that only has DOWN." meaning that they are specifically asking a mathematical question regarding the building they live in as a fun puzzle. Lack of context is not present here. Can someone provide details on why this was closed?
@amWhy it seems reasonable as a decent canonical question for users to better learn how to increase their rep without damaging the site. After all, the best way to earn rep should be by actually contributing. Though that seems to not be the case around here....

Are you there @TheGreatDuck ?
yes
why
@galmeida?
could you please review an a response I made? Is about elementary modular arithmetic
for any mistake

A: Concrete Mathematics: Understanding Modular Arithematic

galmeidaWe want to prove that the following sequence: $$0, 1n, 2n, ... , (m-1)n \; (mod\; m)$$ Is equal to the sequence:$$0,d,2d, ... ,(m'-1)d$$ In some order, repeated $d$ times. Where $d=gcd(m,n)$. Assume $m=dm'$ and $n=dn'$. They do it in two steps: 1) Prove that the sequence $0, 1n, 2n, ... ...

@amWhy PSQ linked above.
@galmeida please do not answer PSQs
thank you

For deletion: D1, D2, D3.
Is it really PSQ? He is asking for a more explicit derivation of the solution using the given identities. That would be like "Given A, show that B" kind of question
@galmeida he doesn't say why he is asking the question so it is unclear whether it is a homework question or requiring a citation
it would be closed for lack of context imo
such questions are not supposed to be answered
I've heard rumors of a rule potentially being put on the books at some point but I don't know if that will ever come to fruition or not. Best to refrain. Don't delete the answer though. That will do more harm than good. Just be more careful in the future.
@galmeida unfortunately I don't know enough about the subject to be able to comment on whether the information in your post is correct. Mathjax wise and paragraphing wise it looks fine though. Nothing stands out to me. It is definitely above my level though in number theory stuff. I'd look for someone with experience there if you need actual feedback on correctness.
However, my opinion of it being a PSQ might also be wrong, but it is better to alert others and find out one is incorrect then to ignore it and allow the post to clog up the site.

HNQ has already been addressed before (See comment by Carmiester)
Bad HNQ
Poor HNQ

Blatant PSQ
Two-year old aPSQ from same user with 2 upvotes and upvoted answers.
Seems like no one gave him the message.
From same user - PSQ1, PSQ2
All they ever seem to have done is add PSQ's, sigh.

@DevashishKaushik Close
@DevashishKaushik I have voted to close all those HNQs and PSQs (with one exception, since it was already closed).
