Think of a number. Any number at all... between 10 and one billion.
Now, since that number has at least two digits, add up all of the digits, and subtract that sum from your original number.
Next, add up all of the digits of the number you just got after that subtraction, to get another new number. And then do it again with THAT number (if you have only a one-digit number, you would just get that same number again).
Finally, subtract 1 from that last number, and find the letter of the alphabet that corresponds to the result (1=A, 2=B, 3=C, etc.) Now think of one of the 50 United States...
