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.
Digit. A digit is a single symbol used to make numerals. 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are the ten digits we use in everyday numerals. Example: The numeral 153 is made up of 3 digits (1, 5 and 3). Example: The numeral 46 is made up of 2 digits (4, and 6).Example: The numeral 9 is made up of 1 digit (9). So a single digit can also be a numeral. So digits make up numerals, and numerals stand for an idea of a number.Just like letters make up words, and words stand for an idea of the thing. number is a count or measurement, that is really an idea in our minds. We write or talk about numbers using numerals such as 4 or four. But we could also hold up 4 fingers, or tap the ground 4 times. These are all different ways of referring to the same number.
