Quotation marks in Beamer

Question

I have something like this

\documentclass[xcolor=svgnames]{beamer}
\usecolortheme[named=Crimson]{structure} 
\usetheme[height=7mm]{Rochester} 
...
\begin{document}
\begin{frame}
In fact
\begin{align*}
  ``Formula''
\end{align*}
\end{frame}
\end{document}

(the Formula needs to be in math mode) and I get

What am I doing wrong?

Answer 1

Because you are inside math mode, the single quote character has a different meaning. Since quotation marks proper are part of the text, a better way to do this is to use the amsmath \text command. Since you want to put an actual math expression inside the quotation marks you need to put just the quotes themselves in the \text{} macro. If this is something you might do often, then turning it into a macro might be a good idea too.

\documentclass[xcolor=svgnames]{beamer}
\usecolortheme[named=Crimson]{structure} 
\usetheme[height=7mm]{Rochester} 
\usepackage{amsmath}
\begin{document}
\begin{frame}
\begin{align*}
  \text{``}a^2 + b^2 = c^2\text{''}
\end{align*}
\end{frame}
\end{document}
