Re: Conjugate

To have an Element statement applied it would have to be used as an assumption along with a command that can use assumptions (e.g., Simplify, FullSimplify).
Assuming[Element[{A, B}, Complexes], FullSimplify[Conjugate[A + B] == Conjugate[A] + Conjugate[B]]]
True
FullSimplify[Conjugate[A + B] == Conjugate[A] + Conjugate[B], Element[{A, B}, Complexes]]
True
However, this Assumption is unnecessary.
FullSimplify[Conjugate[A + B] == Conjugate[A] + Conjugate[B]]
True
