Complex conjugate of what?

Complex conjugate of any complex number is found by changing the sign of imaginary part, i.e, from positive sign to negative and from negative sign to positive.

Let $a + i b$ be any complex number then its complex conjugate is $a - i b$.

And if $a - i b$ is any complex number then its complex conjugate is $a + i b$.
