Hello again. Here's another question: The documentation says that replace replaces "matching subexpressions of self with value" and subs does "substitution of subexpressions as defined by the objects themselves".
Unfortunately I am not totally able to comprehend the difference between the two. Can you please give an example for each where the other will not work? (BTW as an aside, in some places in the documentation like p 502 (508 of PDF) what is apparently a terminal transcript such as ">>> from sympy.matrices import" etc are not properly formatted -- just thought I'd mention.)
