Im sorry, I don't really get that. How would I go around starting to answer the Q2? I know that O' = O But how would I show that O+O' is hermitian?

1.What does it mean for an operator to be hermitian? Note: the dagger is represented by a ' 2. How do I show that for any operator ie/ O' that O + O' , i(O-O') and OO' are hermitian? Thanks in advanced
