[Tutor] deciphering code

Nope, not me - too lazy!
But it seems that several of your questions are answered
(in Scheme) in the book "Structure and Interpretation of 
Computer Programs" by Abelman and Sussman(s). It might 
be useful to find a copy (in a local college library maybe?)

Specifically chapter two covers symbolic algebra including 
addition, multiplication and derivation of polynomials...
