Definition. Number is a grammatical category of nouns, pronouns, and verb agreement that expresses count distinctions (such as one or more than one). The count distinctions typically, but not always, correspond to the actual count of the referents of the marked noun or pronoun.
These three numbers are not three digits; they are numbers made of digits. (e.g. 21 has two digits just as 480 has three digits.) A digit is a numeric symbol (such as 2 or 5) used in combinations (such as 25) to represent numbers (such as the number 25) in positional numeral systems.
