There is an error in the c value. It should be c = + - . The statistic c is related to the winning probability of CHSH game, you should not arbitrarily change the sign of its parts. (Pr(win) - Pr(Lose) = c / 4)

I think we can exchange a and a' arbitrarily because we haven't yet defined what they are, which means it is just a matter of convention. (In fact, with your definition, you can still prove the same inequality using |x+y|

No,His explanation is right.We can change the sign of CHSH inequality's parts.
