title: Finding SUM except some columns
body: <p>Below is what I have.</p>
  
  <pre><code>+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
  +  A  +  B  +  C  +  D  +  E  +  F  +  G  +  H  +  I  +  J  +  K  +
  +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
  +  1  +  2  +  3  +  4  +  5  +  6  +  7  +  8  +  9  +  10 +  50 +
  +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
  </code></pre>
  
  <p>To find the <strong>SUM</strong> of this row excluding <code>Cell E</code> I am using formulae as below.</p>
  
  <p><strong><code>=SUM(A1:D1)+SUM(F1:J1)</code></strong></p>
  
  <p><em><strong>NOTE : <code>Cell K</code> have SUM.</em></strong></p>
  
  <p>Is there any alternate way??</p>
  
  <p>Above is just an example however in my sheet there are around 100 columns and I need to exclude around 10-15 columns.</p>
