It's no secret that a lot of the people out there don't know enough LaTeX. Maybe they were never exposed to it, or maybe they are just unaware of the fact you can use MathJax on the site.
So sometimes you see posts written with "ASCII math standards" For example "*x^(2.5)+2*sqrt(6y-1)=phi/pi*". The correct LaTeX-ification would be $x^{2.5}+2\sqrt{6y-1}=\frac\phi\pi$.
But sometimes you see people who just, perhaps lazily, add dollar signs around equations, and the result is $x^(2.5)+2*sqrt(6y-1)=phi/pi$. Or sometimes they recognize some of the additional slashes and braces and the result looks like $x^(2.5)+\sqrt(6y-1)=\phi/\pi$.
Assuming that you don't have the energy to correct the LaTeX yourself. What should be done with the edit? (Reject/Approve/Ignore?)
\displaystyle
from the title), but I will sometimes review edits that only add dollar signs here and there and in an often haphazard sort of way. I usually reject such edits (or sometimes reject and edit), but many of these kinds of rejects contribute to a somewhat more harsh edit suggestion record (currently 506 approved, 540 rejected). $\endgroup$\frac\phi\pi
(or\frac{\phi}{\pi}
to those bothering to add even redundant braces) is better... :-) I actually wondered if someone will comment about this! $\endgroup$$42$
in order to get the digits into the same typeface that is used for more complex formulas in the post -- but there's no reason at all to change42
to$42$
if the post doesn't contain any complex formulas that the plain body font's digits could clash with. $\endgroup$
