Numbers are one kind of determiner . In terms of meaning, numbers are similar to quantifier determiners, but most grammarians treat them separately.

Numbers can be "cardinal(one, two, three) or "ordinal(first, second, third), as shown in this table:

Like all determiners, numbers come at the beginning of a noun phrase, so they come in front of any adjective(s).

Look at these example sentences:

  • I ordered two cakes.
  • There were three hundred angry people present.
  • Jane won first prize  and Jo won third prize.
  • They have just produced their one millionth sports car.

When used together in a noun phrase, ordinals normally come before cardinals.

  • The  first three prizes  went to the same family.
