oth values into variables by putting the first variable name, a comma, then the second variable (<code>bigger, smaller =</code>).
We don&apos;t need to capture everything returned from a function.

<pre><code class="lang-lua">bigger = sort_numbers(<span class="hljs-number">12</span>, <span class="hljs-number">18</span>)
</code></pre>
