# Appendix numbering (Alph.arabic) in Latex [closed]

I'm trying to have a appendix as

Appendix A

A.1 A.2 A.3

This is what I have do so far

\appendix
%\renewcommand\thesection{\Alph{subsection}}
\renewcommand{\thesubsection}{\arabic{subsection}}


Can anyone please tell me what I'm doing wrong here??

Thank you

• What document class are you using? – Alan Munn Sep 2 '15 at 15:59
• For article the A.1 numbering style is the default as soon as \appendix and \subsection is used, there is no need of redefinition of the \the... macros. It requires a non-zero section counter value however, since \Alph{section} outputs nothing if section is zero – user31729 Sep 2 '15 at 16:42

If the article class is used, there is no need of \renewcommand{\thesubsection}{...} since \appendix redefines \thesection to use \Alph etc.

\documentclass[a4paper,10pt]{article}
\usepackage{blindtext}
\begin{document}
\tableofcontents
\blinddocument
\appendix

\section{An appendix section}
\subsection{An appendix subsection}
\subsection{Another appendix subsection}
\section{Another appendix section}
\subsection{Just another appendix subsection}
\subsection{Yet Another appendix subsection}

This is an appendix.
