How to think about Map[ ] ?
Posted:
Aug 21, 1996 2:06 AM


I can understand that
Map[f,{a,b,c}] > {f[a], f[b], f[c]}
But would someone want to give a little tutorial on how to understand the (what seem to me) bizarre results I get when I try various combinations like
Map[f, a + b + c]
Map[f, a + b  c]
Map[f, a * b * c]
Map[f, a / b / c]
and other more complex forms. (I'm particularly confused by the difference between the * * and the / / cases. I'm not acquainted with LISP, and have never encountered any other form of mathematics that operates as Map seems to.)
Thanks...
