title: examples to compare tradtional math notations vs APL/J notations
body: <p>I am reading a review to compare <a href="http://archive.vector.org.uk/trad/v224/v224-IAN/clark.htm" rel="nofollow">Mathematica to APL/J</a>. One question raised in the article seems very interesting to me:</p>
  
  <blockquote>
    <p>Is Mathematica really the way to go to express our creative thoughts –
    viz back to a 17th century notation designed for parchment instead of
    forward to a twentieth-century one designed for computers?</p>
  </blockquote>
  
  <p>Can one share examples of Iverson's notation vs traditional math notation to demonstrate the edge of APL/J on expressing and solving math problems? This would be greatly helpful for new comers.</p>
