I need to prove that the set of all hermitian matrices Mh with operation "+" forms an additive group. I know that the set of all matrices M with additive operation forms an additive group(I proved that). My question is, if I prove that set of hermitian matrices with additive operation Mh is a subgroup of M, is it a good proof that Mh is a group (or I should prove every group property separately)? Thank you
