Same effect you showed. It might be because subscript are meant to be applied to an atomic symbol and not combined expression like a+b. I do not know. I am not even sure what (a+b)_k is supposed to mean, math wise. Is this meant to be on the code or in a text cell? If it is in the code itself, how will it be used? --Nasser
