+You can typeset matrices and other similar objects using an \texttt{array} environment. A couple of things to note:

+\begin{itemize}[noitemsep]
+ \item \texttt{array} can only be used in a math environment.
+ \item You must declare the number and alignment of the columns by using \verb+\begin{array}{ccl}+. In this instance, we are declaring two centered columns and one left-aligned column.
