<h1>% (Modulo)</h1><br />
<p>a % b returns the remainder when a is divied by b </p><br />
<p>If you use a % 2 you get 0 for even numbers and 1 for odd numbers.</p><br />
<p>If you use a % 10 you get the last digit of the number a. </p><br />
<pre style='width:50ex'><br />
27 % 2 -> 1<br />
27 % 10 -> 7<br />
</pre><br />
<br />
<div class='ht'><br />
In this example you get the final digit year of the games. <br />
