Hey everyone, I had two simple questions, and was wondering wether anyone could through something my way: 1) When we have a list, call it AList, and we type the following AList /. {rule1} AList /. rule1 what is the difference between the two? And, how would I go about defining a rule for the variable AList, and a rule for the contents of the list - obviously these are two different concepts, yet how would you differentiate b/w the two? Thanx to all MR
