LaTeX is a software system for document preparation. LaTeX attempts to follow the design philosophy of separating presentation from content, so that authors can focus on the content of what they are writing without attending simultaneously to its visual appearance.
Latex is widely used in academia for the communication and publication of scientific documents in many fields.
We can use overleaf to practice working on LaTeX. One of the sample code and the sample output is shown below:

\documentclass{article}
\title{My first document}
\date{2013-09-01}
\author{Author}
\begin{document}
\pagenumbering{gobble}
\maketitle
\newpagee
\end{document}
Hello world
\end(document}
