title: How do properly use css's "calc()' with ng-style
body: <p>I have the following inline-styling using Angular's ng-style and css's "calc()', but it didn't work. Can anyone tell me what's wrong?</p>
  
  <pre><code>// my jade file has a class named '.logo-area'. 
  .logo-area(ng-style="{'right':'calc(100% -'+({{fixedWidth}}+'px') +')'}")
  </code></pre>
