So I'm writing a report using Latex and the document class I am using is report: \documentclass[a4paper]{report}
But for some reason the section numbering is written so that it is preceded with "0.", for example it looks like:
0.1 Introduction
0.2 Theory
0.3 Experimental Method
and so on.
Can somebody help me get rid of those zeros so that it appears how it is supposed to be?
report assumes you'll be using \chapters as your main sectional unit. As such, all sectional units are marked "relative" to the \chapter counter. Specifically, \section counters are set using \thechapter.\arabic{section}. Either use
\documentclass[a4paper]{article}
to remove any reference of \chapters, or add
\renewcommand{\thesection}{\arabic{section}}
to your document preamble.
The former would have greater impact on the actual output, as the setting of a \title and possibly the layout may be different. The latter would just remove the \chapter counter from being printed with every \section (and lower-level section unit).
\chapteras first level. If you don't need chapters you possibly use the article class. – Christoph
