<p>In particular, to increase your chances of having your question answered instead of closed:</p>
<ol>
<li>explain the context of your problem (where is it from),</li>
<li>state your problem clearly,</li>
<li>show your attempt at solving your problem, and</li>
<li>explain where you are stuck or confused.</li>
</ol>
<p>DO NOT simply write a question with &quot;PLZ HELP!&quot;</p>

<p>To get started, try:</p>
<ol>
<li>putting <code>$</code> on either side of math, as in <code>$1+2$</code></li>
<li>using <code>^</code> for superscripts and <code>_</code> for subscripts, with <code>{ }</code> to group multiple characters, as in <code>$3^{1+2}$</code> for <span class="math-container">$3^{1+2}$</span></li>
<li>using <code>\frac{ }{ }</code> for fractions, as in <code>$\frac{4}{5}$</code> for <span class="math-container">$\frac{4}{5}$</span></li>
<li>using <code>\alpha, \beta, ...</code> for greek letters</li>
</ol>
<p><code>$$\frac{ x_{n+1} + \alpha }{ x_n + \beta } = \gamma^3$$</code> would render like this:</p>
<p><span class="math-container">$$\frac{ x_{n+1} + \alpha }{ x_n + \beta } = \gamma^3$$</span></p>
<p><span class="math-container">$\LaTeX$</span></p>
