**MathJax Syntax**

To add an inline equation wrap your equation in \$ tags.
Stand-alone equations should be wrapped in double \$\$ tags. To have equations numbered use `\begin{equation} ... \end{equation}`, without \$ tags.


Inline equation:
`$ x^2 $`

How it shows:
$ x^2 $


Stand-alone equation:
`$$ x^2 $$`

How it shows:
$$ x^2 $$

A peculiarity to keep in mind. Use
`$1\lt 2$`  or `$1< 2$` (notice space after "<" sign to avoid being interpreted as HTML tag)  to produce 

$1\lt 2$


Numbered equation:

	In equation \eqref{eq:sample}, we find the value of an
	interesting integral:

	\begin{equation}
  	\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
  	\label{eq:sample}
	\end{equation}

example of LaTeX table:
$$
\begin{array}{c|lcr}
n & \text{Left} & \text{Center} & \text{Right} \\
\hline
1 & 0.24 & 1 & 125 \\
2 & -1 & 189 & -8 \\
3 & -20 & 2000 & 1+10i \\
\end{array}
$$

and another one:

$$
% outer vertical array of arrays
\begin{array}{c}
% inner horizontal array of arrays
\begin{array}{cc}
% inner array of minimum values
\begin{array}{c|cccc}
\text{min} & 0 & 1 & 2 & 3\\
\hline
0 & 0 & 0 & 0 & 0\\
1 & 0 & 1 & 1 & 1\\
2 & 0 & 1 & 2 & 2\\
3 & 0 & 1 & 2 & 3

% inner array of maximum values
\begin{array}{c|cccc}
\text{max}&0&1&2&3\\
