title: Simple math on SQL query results or on a datatable
body: <p>Let's say I have a query that returns something simple like...</p>
  
  <pre><code>**TYPE**      **TOTAL**
  A                2
  B                4
  </code></pre>
  
  <p>And I want to do some math like A/(A+B) -> 2/(2+4) then display that on my website. Is that more feasible to do within the query or after when I have it stored in a datatable?? </p>
