How to reduce or make the space equal of linespacing before and after the $$ something $$ ?
1 Answer
The use of $$...$$
is depricated in LaTeX. Instead you should use \[...\]
.
You can change the spacing before an after by doing something along the following lines:
\abovedisplayskip0pt
\belowdisplayskip0pt
\abovedisplayshortskip0pt
\belowdisplayshortskip0pt
\[x+2y-5z=0\]
`
, they'll be marked as code, as can be seen in my edit. You can also highlight the code and click the "code" button (with "{}" on it).
