Shoe Math Magic

Have you tried this math trick that figures out your shoe size and age in six easy steps?

  1. Take your shoe size (no half size, round up)
  2. Multiply it by 5
  3. Add 50
  4. Multiply by 20
  5. Add 1016
  6. Subtract the year you were born

The first digits(s) is your shoe size; the last two are your age.  Please note – this trick won’t work for a person who is 100 or more; also, if a person has already had a birthday this year when you present this challenge, the age will be off by one year.

Keep your fork
