title: String with math operators to Integer
body: <p>I have a string with math operators which I need to turn into an <code>int</code> (the answer).</p>
  
  <p>The below code does not work, but I'm not sure how I can get the answer variable to work.</p>
  
  <pre><code>String question;
  int answer;
  
  question = "7/7+9-9*5/5";
  answer = Integer.parseInt(question);
  </code></pre>
