What does *-1 means?
<p>I don't know how to find keyword for this (*-) in Google, and I don't know what is name. So I ask here.  </p>

<p>Sample code :</p>

<pre><code>StartDate:=IncMinute(FinishDate,TotalMinutes*-1);
</code></pre>

<p>What is <code>TotalMinutes*-1</code> if I write in 'normal' syntax ?</p>
