Generally it is alright to use language that otherwise would seem vulgar or offensive if it is established/technical usage, for example Stack Overflow has an entire tag brainfuck, because somebody thought it was a good name for a programming language.
Things to keep in mind:
Make it amply clear that this is established usage.
Rather avoid to put such ...

No. $\displaystyle\sum_{x}^{y}$ is not an improvement over $\sum_{x}^{y}$. Display style mathematics should be used in displays, and in a diminishingly small number of other circumstances. Display style math in an inline context stretches the vertical space on that line (which makes the line spacing inconsistent; see above), and is generally considered ...

Disclaimer: I was your only upvoter on that question when I posted this, and I have provided an answer to it, so some people may consider me biased.
It's impossible to know why you get a downvote unless the downvoter explains themselves, so the best we can do is make educated guesses. My recollection is that you received the first downvote before you added ...

Reasons it is unlikely to be looked at favorably:
It spaces lines out way more than required ( and can create typographical widows)
It can usually be replaced altogether with something that will fit inline ( like $x_n+\cdots+x_1$)
Making it tinier to avoid using inline math, just makes it hard to read ${\tiny{\displaystyle\sum_x^y}}$ for example.
You didn'...

We should keep these problems, because you never know when you have one.
Some days ago, user Nikita asked the question Is this contrived sequence eventually periodic?. Innocently enough, they explained that they had built quite a weird sequence $A(n)$, which seemed to have a period, as all residue classes mod $6$ except for one gave the exact same thing. I ...

Like most math problems. That's what they are. You can compute asymptotics of the code you create etc.
The first problem listed, is equivalent to asking if:$$\binom{9n}{n}\cdot\binom{8n}{n}\cdot\binom{7n}{n}\cdot\binom{6n}{n}\cdot\binom{5n}{n}\cdot\binom{4n}{n}\cdot\binom{3n}{n}\cdot\binom{2n}{n}\cdot (n!)^9+n!+1$$ can be prime.
Which is quite the ...
