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...
