Notes:

  • The numbers 13 to 19 use a variation of the numbers 3 to 9 plus "teen," which means "ten." This is where the words "teenager" and "teen" come from – they refer to someone who is between 13 and 19 years old.
     
  • Beginning with 21, you have to put a hyphen between the two numbers: thirty-four, ninety-six, fifty-three.
     
  • "Four" has a u but "forty" does not.
