title: Javascript Sum Values
body: <p>I need to sum several values in javascript. I've tried by using following code</p>
  
  <pre><code>var a = 2;
  var b = 5;
  c = a+b;
  </code></pre>
  
  <p>But, instead of calculating the values of a and b, the output (c) only combine those two values. So the output given is :</p>
  
  <pre><code>c = 25
  </code></pre>
  
  <p>I believe you guys can help me easily about this. Thx before. Regard Andha.</p>
