Does the complex conjugate just switch the sign in-between the numbers?

Question

I have a question about imaginary numbers and their complex conjugate.

My teacher denotes the complex conjugate to have a bar over it. For example: $\overline{3+5i} = 3 - 5i$

But does the complex conjugate just switch the sign in-between the numbers?

For example, would $\overline{-1 - i} = -1 + i$ ?

Answer 1

It just switches the sign of the imaginary part of the number. Your example is correct.
