title: How to calculate function points
body: <p>This is a question about theoretical computing. I have came through a question like below;</p>
  
  <p>Consider a project with the following functional units :</p>
  
  <ul>
  <li>Number of user inputs = 50</li>
  <li>Number of user outputs = 40</li>
  <li>Number of user enquiries = 35</li>
  <li>Number of user files = 06</li>
  <li>Number of external interfaces = 04</li>
  </ul>
  
  <p>Assuming all complexity adjustment factors and weighing factors as average, the function points for the project will be;</p>
  
  <p>The answer is 672. How is this calculated?</p>
