A good way to learn exactly what these mapping operations do is to look 
at the "visual definitions" for some of them at:

  http://www.mathematica.co.kr/mathcomm/20_definitionviz/index.html

I believe that a similar thing appears on the Wolfram web site, but I 
can never find it there when I search.
