The Magic Cafe Forums - Numeric force...

There's a mathematical force that results in a number divisible by 9 in which someone thinks of a two digit number, adds the two digits together to make a 2nd number and then subtracts that from the first number to arrive at the number they will use.

The answer will be one of 9, 18, 27, 36, 45, etc.

Can someone tell me where this first appeared or any history on it? It was used fairly recently in a marketed trick but I'm positive I've seen it prior to that maybe even used on TV in one of those "join in at home" type tricks.
