The basic structure of a Prosper input file is pretty simple. Consider the file sample.tex, the content of which is shown below:
% sample.tex
\documentclass[pdf,azure,slideColor,colorBG]{prosper}
\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}
\end{slide}
\end{document}
The input file above produces the following single slide:
![[image]](sample-azure.png)
The \begin{slide}{}...\end{slide} block can be repeated any number of times to produce a sequence of slides.
\begin{slide}{Elementary mathematics}
specifies "Elementary mathematics" as title for this slide. It is an error to omit the slide title.
