This beamer attempt produces the error "Too many math alphabets used in version normal.". Using the article class produces no error as does removing either chemmacros or siunitx, but I need those packages.

\documentclass{beamer}

\usepackage{chemmacros}
\chemsetup{greek=fourier}

\usepackage{siunitx}
\usepackage{helvet, mathpazo}%suggested by siunitx


\begin{document}
\begin{frame}
\num{1+2i}
\end{frame}
\end{document}

    not sure why you need so many fonts, but using xelatex or lualatex is one option as the document runs without error then. – David Carlisle Mar 30 '16 at 20:07
  • I just used some of the packages the siunitx documentation suggests. Removing the \usepackage{helvet, mathpazo} line throws a single error, while keeping it throws two. At this point I'm considering to give up on pdfLaTeX and use XeLaTeX. – Kurzd Mar 30 '16 at 20:18

Add \usefonttheme{professionalfonts}. Compiles for me, then.

\documentclass{beamer}
\usefonttheme{professionalfonts}
\usepackage{chemmacros}
\chemsetup{greek=fourier}

\usepackage{siunitx}
\usepackage{helvet, mathpazo}%suggested by siunitx


\begin{document}
\begin{frame}
\num{1+2i}
\end{frame}
\end{document}
