Katie: Daddy.
Mike Enslin: No, you're not real.
Katie: I'm cold.
Mike Enslin: No, you're not Katie.
Katie: I love you Daddy. Don't you love me anymore?
Mike Enslin: Of course I do, sweetheart.

Question: When Mike gets a postcard about the Dolphin and room 1408, he writes on the back for a moment as he figures something in his head and circles a (=13). He then says cute. How exactly did he figure 13 from 1408? I am confused by that part.
