I want to have numbered sections in an unnumbered chapter.
This is my code:
\documentclass{book}
\begin{document}
\tableofcontents
\chapter*{Introduction}
\addcontentsline{toc}{chapter}{Introduction}
\section{First numbered section in unnumbered chapter}
\section{Second numbered section in unnumbered chapter}
\chapter{First numbered chapter}
\section{First numbered section in numbered chapter}
\end{document}
This is a preview of the compiled Table of Contents:
As you can see the numbered sections have leading zeroes in the Table of Contents. How can I delete the leading zeros? Of course I want to achieve the same in the actuel text.
Thank you
