\section{Math Testing}
\label{mathtesting}

You can use math in-line, such as $ {\displaystyle 8+4=12}$ and $ {\displaystyle \frac{155}{12}=\frac{10}{2}}$. 

Or you can use as paragraphs:

\begin{equation}
{\displaystyle \frac{155}{12}=\frac{10}{2}}
\end{equation}

\begin{equation}
{\displaystyle {x}^{2}+{y}^{2}=1}
\end{equation}

Or with a blockquote-like syntax:

\begin{equation}
{\displaystyle {x}_{1,2}=\frac{-b\pm \sqrt{{b}^{2}-4ac}}{2a}}
\end{equation}

Code is not translated: \texttt{x = pi}
