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.)
