 \begin{document}
 
 \begin{slide}{Elementary mathematics}
 
 Observations:
 
 \[
     \int_{-\infty}^\infty e^{-x^2} \, dx =
     \sqrt{\pi}
 \]

 \[
     e^{i\pi} = -1
 \]
 
 Conclusions:

 \begin{itemize}
     \item $\sqrt{2}$ is irrational
     \item $e$ and $\pi$ are transcendental
     \item $42$ and 42 are not the same in \LaTeX
 \end{itemize}
