How do I remove a number before a section in latex

Question

`\chapter*{Chapter 2} \section{Literature review} \subsection{Introduction}

results: Chapter 2 2 literature review 2.1 Introduction

I want that 2 before the literature review removed

I am expecting to get something like this:

results: Chapter 2 literature review 2.1 Introduction`

Answer 1

If you add a '*' after 'section' but before '{Literature Review}', like

\chapter*{Chapter 2} \section*{Literature Review} \subsection{Introduction}

It should force LaTeX to skip over the automatic numbering scheme.
