Math Magic

THE EFFECT: You ask your spectator to think of a number they can easily multiply with. You make the spectator do some mathematical equations, then you're able to tell them their final number by reading their mind!


THE SECRET: After your spectator thinks of a number, tell him to multiply it by nine. After that tell him to add the digits of his answer together and that will be his final number.


For an example tell them that if their number is twenty one. Two plus one equals three. Three would be their answer.


Ask how many digits is in their answer. If it is more than one tell them to add the digits of their answer until the answer has only one digit left.


The spectators last answer will always be NINE!
