Question

Starting from the general definition of an adjoint operator, show that for any 2 operators A and B then: 

(A+B)* = A° + B',
(AB)† = B† A*,
(AA)† = XA',
where A is a complex number and AŤ indicates the adjoint of A.
From above with an additional operator C, what would (ABC)† be equal to ?
