It would have been better if instead of syncing the camera with the prof, a wide angle frame would have been used keeping the content on the board steady!!

Regarding the question at 20:00 : Which I believe was "[We also need] f(1)=1". To which the answer was that we do not need to specify this because "it's already there in M", "there is no f(1) there, and both of them are modules over A". I would just like to know what is meant by this? My own guess is that we would not need to specify this since we do not have 1 \in M per se, since the only binary operation on M is +, and 1 only make sense as an element of A, so to specify f(1)=1 makes no sense. But I'm not sure what the Prof. really means by his remarks. Anyone else?
