With these thought-reading tricks may be put one or two arithmetical
puzzles. Here is a way to find out the number that a person has
thought of. Tell him to think of any number, odd or even. (Let us
suppose that he thinks of 7.) Then tell him to double it (14), add 6
to it (20), halve it (10), and multiply it by 4 (40). Then ask him how
many that makes. He will say 40. You divide this in your mind by 2
(20), subtract 6 (14), divide by 2 again (7), and astonish him by
saying that the number of which he thought was 7.
