  1. Pick any number between 1 and 15;
  2. multiply that number by 2;
  3. add 3 to the result;
  4. double the result;
  5. subtract 10 from the result;
  6. multiply the result by 10;
  7. divide the result by 2;
  8. add 6 to the result;
  9. divide the result by 2;
  10. multiply the result by 5;
  11. multiply your original number by 2, and add it to the result;
  12. add 1 to the result;
  13. divide the result by 2;
  14. square the result;
  15. add 25 to the result;
  16. square your original number, and subtract it from the result;
  17. add 100 to the result;
  18. divide the result by 7;
  19. take the third root of the result; and, finally,
  20. multiply the result by 0.
The answer will always be zero.
