How to list items in LaTeX: itemize, enumerate

The itemize environment and item command creates a unordered list of items in LaTeX. Each item starts with a black circle.

\documentclass{article}
\begin{document}

\noindent Algebraic structure
\begin{itemize}
  \item Group
  \item Ring
  \item Field
\end{itemize}

\end{document}

The item command can take curly brackets and long texts with a new line.

\documentclass{article}
\begin{document}

\noindent For example:
\begin{itemize}
  \item Group
  \item{Ring}
  \item{  Field}
  \item{ $\frac{2}{5}$ = 0.4 }
  \item Lorem Ipsum is simply dummy text of the printing and typesetting industry.

Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,
when
an
unknown printer took a galley of type and scrambled it to make a type specimen book.
\end{itemize}

\end{document}

The spaces before or after texts in \item are ignored.

Numbered list

The enumerate environment displays a numbered list of items.

\documentclass{article}
\begin{document}

\noindent For example:
\begin{enumerate}
  \item Group
  \item{Ring}
  \item{  Field}
\end{enumerate}

\end{document}

Using the command \setcounter enables a numbered list to start from $n$.

\documentclass{article}
\begin{document}

\noindent For example:
\begin{enumerate}
  \setcounter{enumi}{5}
  \item Group
  \item{Ring}
  \item{  Field}
\end{enumerate}

\end{document}
