What is a "cardinal number"?

A cardinal number is a number that indicates quantity and is used to count items. Cardinal numbers answer the question "how many?" and are fundamental in expressing amounts. Examples of cardinal numbers include "one," "two," "three," and so on. For instance, in the phrase "three apples," the cardinal number "three" specifies the exact quantity of apples being referred to. Cardinal numbers are essential for everyday counting, providing a clear understanding of quantities and helping to convey specific information about numbers in various contexts.
