ELI5: When there’s a mirror scene in a movie or television show, how do they get the shot without showing the camera in the mirror, especially with a head on face shot?

The "head on" face shots are actually shot at a slight angle.  So the actor is looking at the camera in the mirror, and not at themselves.

And in cases where it's absolutely impossible to shoot the mirror at an angle, they just edit out the camera using computer software in post-production.
