Puzzle Solution
Herein lies the explanation for the success of the Mathematical Magic Trick.
For each step of the directions, the possible results are shown within brackets.
1) Pick a number from 1 to 10. [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
2) If greater than 5, subtract 5. [1, 2, 3, 4, 5]
3) Then multiply by 3. [3, 6, 9, 12, 15; all multiples of 3]
4) Now square the number. [9, 36, 81, 144, 225; all multiples of 9]
5) Then add the digits together.... [9; for any multiple of 9, the sum is 9]
6) Now subtract 4. [5]
7) Then multiply by 2. [10]
8) Now subtract 6. [4]
9) Then map the number to the corresponding letter.... [D]
10) Pick a country beginning with that letter. [most likely Denmark, Dominican Republic]
11) Take the second letter in the country name and think of a mammal.... [elephant, elk]
12) Think of the color of that mammal. [gray, brown]
There's a very good chance you have a grey elephant from Denmark!
