title: Assemble handlebars nested math helpers
body: <p>I was wondering whether there is a way to combine two <strong>[Assemble Math helpers]</strong><a href="http://assemble.io/helpers/helpers-math.html" rel="noreferrer">1</a> in one operation.</p>
  
  <p>For example:</p>
  
  <ul>
  <li>I want to do <code>{{multiply 12 a}}</code> and then</li>
  <li>do <code>{{round}}</code> on the resultant</li>
  </ul>
  
  <p>Thanks for any help.</p>
