How can i number subsections. I do want them in form like 2.0.1. I want them in form like 2.1?

\documentclass[12pt]{report}
\usepackage{amsmath}

\begin{document}

\title{\LARGE Chapter 2}

\chapter{\LARGE Introduction.}

\subsection{How are you}

\end{document}


Just don't use subsections, but sections: \section{bla}.
