Pick A Number - I'll Read your mind.


The Problem...
   1. Pick a 3 or 4 digit number, not all the same digits.
   2. Jumble up the numbers.
   3. Subtract the smallest number from the largest.
   4. Draw a circle around one of the numbers (it can't be a zero).
   5. Jumble up all the non-circled numbers; write down the result.
   6. The mind reader can tell you what the circled number is.
