title: java result really different from the expected one
body: <p>I'm trying to output a really simple value, but what I obtain is really weird:</p>
  
  <pre><code>Log.d("try", "distanceWithMaxSpeed &gt; " + ((90 * (1000 / 3600)) * ((3000 - 2000)/1000)) );
  </code></pre>
  
  <p>I get 0 instead of 25! Where am I wrong?</p>
