1. First, tell somebody to write a 3 digit number, and tell them not to show you or tell you what it is. Make sure you tell them that the number cannot be the same backwards. Ex: 132 (545, 737, or 111,any number that is like 101 would not work would NOT work).

   Next, tell the person to find the difference of the number he/she wrote down and the reverse of this number by subtracting the smaller number from the larger number: Ex:231-132=99

   .
4. 
   Now, have the person add the new number to the reverse of that number. If the new number has two digits add a zero to the beginning: Ex: 099+990=1089
   
   
   

    Now, have the person add the new number to the reverse of that number.

   1089 will always be the end result, so you can amaze your friends with your "mind reading abilities," when you are able to announce what their final number is without looking and without them having to tell you what it is!
