Basic arithmetic seems to work fine. Antiderivatives, much less so. OTOH doing aintiderivatives while awake doesn't work that great for me either. [edit] Though I should clarify that in my dreams I usually finish the antiderivative (wrongly) when awake I usually just fail to finish the antiderivative.
