Examples:

  • Tres pueri in via sunt. = Three boys are in the street.
  • Decem annos habeo. = I am ten years old (literally, I have ten years).
  • Legio quinta. = The Fifth Legion.

For English speakers: a small trap is that most of these numbers do not change their endings. Quattuor through decem are indeclinable, so you will not see the case endings you have learned elsewhere: this is normal, not an error. Only unus, duo, and tres shift form (for example duo, duae, duo and tres, tria). Also note the Roman practice of subtraction in numerals: IV is 4 (one before five) and IX is 9 (one before ten), not 6 and 11.
