The conjugate of the sum of matrices is the sum of the conjugates.

For equally sized complex matrices, $\overline{A+B}=\overline A+\overline B$. This follows from $\overline{z+w}=\overline z+\overline w$ in every entry. Thus conjugation preserves addition, though it is conjugate-linear rather than complex-linear.
