What are the examples of numerical pronouns?

A numerical pronoun can be either cardinal number (one, two) or and ordinal number (first, second) used to take the place of nouns in a sentence. Examples:

Jane bought tomatoes, but two were bad.

The red car was first and the green car was second.

One will be enough.

Note: When a number is placed before a noun, it is a numerical adjective that describes the noun; example: Junior is in the second grade.
