Hi Ondrej, I think one of challenge (please correct me) for using sympy is how I can quickly know which API I should call for the given context? for example, if I need to do subtraction for two symbolic expression, which function I should call without spending too much time to go through the source codes? I think this is also issue even if we call sympy api directly in python apps, any advices?
Thanks.
