I tried this code
```
\documentclass[14pt]{beamer}
%\usetheme{Warsaw}
\usetheme{CambridgeUS}
\usepackage{amsmath}
\begin{document}
\begin{frame}
\verb|Expand[(2 x + 1)^4]|
\end{frame}
\end{document}
```
I can not get the result. How can I use verb in beamer?

If you have problematic content, like verbatim material, in your frame, use the `fragile` frame option:
```
\documentclass[14pt]{beamer}
%\usetheme{Warsaw}
\usetheme{CambridgeUS}
%\usepackage{amsmath}
\begin{document}
\begin{frame}[fragile]
\verb|Expand[(2 x + 1)^4]|
\end{frame}
\end{document}
```
(beamer loads `amsmath` by default, no need to load it a second time)
