I have a slight problem with some parenthesis enclosing unsymetrical stuff. For example, when you type

$$P\left(\overline D\right)$$

you notice that the parenthesis go a little bit too low under the $D$.

Is there a simple, AND automatic, way of dealing with this kind of stuff ? I noticed Adjust vertical alignment of square brackets in equation, but it's really not satisfying if you have to type it everytime...

Thanks for any help.

    You have tagged this amsmath but are you using plain tex rather than latex ($$ and \bye would suggest so)? It usually helps if you provide a complete test document rather than a fragment. here I would simply not use \left and \right, Ithink. – David Carlisle Mar 08 '20 at 12:33

As noted in the accepted answer of the question that you reference, you should not move the delimiters away from the math axis. The problem here is that \left \right makes the parenthesis too large (as well as introducing additional horizontal space). Just using a standard ( produces a better effect both for the size and horizontal space.

enter image description here

\documentclass{article}

\usepackage[fleqn]{amsmath}

\begin{document}

aaa
\[P\left(\overline D\right)\]

bbb
\[P(\overline D)\]

\end{document}

see the discussion in

Is it ever bad to use \left and \right?

  • I use LaTeX, with amsmath (\bye is just an old joke to sign my messages). And I don't find the bar over D being above the edge of the parenthesis... Maybe I'm too narrow minded ;-) – Nicolas FRANCOIS Mar 08 '20 at 13:31
  • @NicolasFRANCOIS jokes are OK but since you also used $$ which isn't LaTeX either, and didn't provide a latex test file (as in this answer) it seemed worth checking. – David Carlisle Mar 08 '20 at 13:51
  • Sorry, I thought $$ was the standard way of writing maths on Tex.stackexchange... – Nicolas FRANCOIS Mar 09 '20 at 12:37
  • @NicolasFRANCOIS the $$P\left(\overline D\right)$$ in your question is an example of tex source code (so would have been better marked as a code block ({} button in the editor) although it is plain tex rather than latex. unlike some other sites in the network this site does not use mathjax to render tex-like syntax as displayed mathematics. – David Carlisle Mar 09 '20 at 12:55
  • @NicolasFRANCOIS, regarding the use of $$, if you use the tag amsmath, you should use the amsmath syntax. Maybe a review of the amsmath user guide would be helpful: texdoc amsldoc. – barbara beeton Apr 07 '20 at 18:00
