<h2>Mathematics support</h2>

<p>You can use <a href="http://en.wikipedia.org/wiki/LaTeX" rel="nofollow noreferrer">LaTeX</a> expression in questions and answers. Simply put the expression within dollar signs. For example, <code>$\sqrt{\alpha+\beta}$</code> produces $\sqrt{\alpha+\beta}$. </p>

<p>Some R code contains dollar signs and to prevent these being interpreted as LaTeX expressions, please enclose all code in single left quotes like this: <code>`fit$x &lt;- model$y`</code>.</p>
