Directions

  • Write down how many days a week you want to go out with your friends.
  • Multiply by two.
  • Add 5.
  • Multiply by 50.
  • If you already had your birthday this year then add 1763. If you haven’t had your birthday this year then add 1762. (Note: these numbers are based on the year 2013. For subsequent years, you must add 1 for each year that passes.)
  • Subtract the year you were born.
  • Now everyone has a 3 digit number (i.e. 324).
  • The first digit is the number of days a week you want to go out with your friends. (3)
  • The next two digits are your age (24).

The questions can be changed to How many times would you like to go out to eat? Or any other How many question.
