To master arcane: I had the same problem learning Maple, but it
is "only" that multiple commands are combined into 1 line, thus
I try to avoid it (and still do it for myself). It simply is too
compact for learning.

I am sure, that Michael Komma can drill it down for you into steps
if you can not succeed starting from the most inner one command
(which is not intended as critics to his replies).
