Thanks Aaron. I roughly understand why assumptions are needed. In my mind: so that sympy knows what the numerical values the symbol can assume. Is that a right way of thinking about it? Is there a document somewhere describing assumptions in general - not related to SymPy but in symbolic math that someone knows of?
