Math & Science ⇒ \overline{f}+ \overline{g}

[avoyance]

\overline{f}+ \overline{g}

the resulting overlines for f and g are not of the same height.
How can I eligently made the equal?

(of course I can raisebox by a few pt. the number is by trial-and-error)

Use an invisible math strut to get even placed lines.

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\newcommand*{\oline}[1]{\overline{#1\mathstrut}}

\begin{document}
  $\oline{f}+\oline{g}$      % good

  $\overline{f}+\oline{g}$   % bad
\end{document}

As you can see from the above code, you have to use the new command exclusively. Otherwise the lines are not placed properly above different strings.
