\begin{abstract}
\LaTeX is a document preparation system.LaTeX is widely used in academia for the communication and publication of scientific documents in many fields, including mathematics, statistics, computer science, engineering, chemistry, physics, economics, linguistics, quantitative psychology, philosophy, and political science. It also has a prominent role in the preparation and publication of books and articles that contain complex multilingual materials.
\end{abstract}
 
  \LaTeX{} is a document preparation system for
  the \TeX{} typesetting program. It offers
  programmable desktop publishing features and
  extensive facilities for automating most
  aspects of typesetting and desktop publishing,
  including numbering and  cross-referencing,
  tables and figures, page layout,
  bibliographies, and much more \cite{LatexBook}. \LaTeX{} was
  originally written in 1984 by Leslie Lamport
  and has become the  dominant method for using
  \TeX; few people write in plain \TeX{} anymore.
  The current version is \LaTeXe \cite{WikiLatex}.

\section{Mathematical expressions}
\begin{equation}
E_0 = mc^2 
\end{equation}

\begin{equation}
 E = \frac{mc^2}{\sqrt{1-\frac{v^2}{c^2}}}
\end{equation}

\begin{equation}
NaOH + HCl \longrightarrow NaCl + H_2O
\end{equation}

\section{Lists}
Convenient and predictable list formatting is one of the many advantages of using \LaTeX. As a mark-up language, \LaTeX gives more control over the structure and content of lists (for more detailes see \cite{WikiLists}). 

\begin{enumerate}
\item The first item
\begin{enumerate}
\item Nested item 1
\item Nested item 2
\end{enumerate}
\item The second item
\item The third etc \ldots
\end{enumerate}


\begin{itemize}
\item more work
\item more responsibility
\item more satisfaction
\end{itemize}

\begin{description}[align=left]
\item[Kate] some detail
\item[Christina]some detail
\item[Laura]some detail
\end{description}

\section{Table}

\begin{table}[htbp]
\caption{Numbers}
\begin{center}
  \begin{tabular}{ | l | c | r |}
    \hline
    1 & 2 & 3 \\ \hline
    4 & 5 & 6 \\ \hline
    7 & 8 & 9 \\
    \hline
  \end{tabular}
\end{center}
\label{numbers}
\end{table}

\subsection{Defining multiple columns}
It is possible to define many identical columns at once (see. Tab. \ref{tab:ManyCols}) using the 
\verb!*{num}{str}! syntax. This is particularly useful when your table has many columns.

Here is a table with six centered columns flanked by a single column on each side: 

\begin{table}[htbp]
\caption{Many identical columns}
\centering
\begin{tabular}{l*{6}{c}r}
Team              & P & W & D & L & F  & A & Pts \\
\hline
Manchester United & 6 & 4 & 0 & 2 & 10 & 5 & 12  \\
Celtic            & 6 & 3 & 0 & 3 &  8 & 9 &  9  \\
Benfica           & 6 & 2 & 1 & 3 &  7 & 8 &  7  \\
FC Copenhagen     & 6 & 2 & 1 & 3 &  5 & 8 &  7  \\
\end{tabular}
\label{tab:ManyCols}
\end{table}
