title: django - multiplication and templates
body: <p>I hope you can help me on this one. I have a template that shows the price of a, lets say a Banana, and for example the banana costs $400 and i have to calculate the 21% of this price and show it on a box of a table. I was tempted to do something like:</p>
  
  <pre><code>{% for banana in bananas %}
  {{banana.price}}*(21%)
  {% endfor %}
  </code></pre>
  
  <p>but obviously that failed miserably.</p>
  
  <p>So, is there a way to do this type of simple equations in a template or i need to make a custom template tag to handle it.</p>
  
  <p>its a very basic question but i would really appreciate the help.</p>
  
  <p>Thank you.</p>
