Cardinal Numbers: Cardinal numbers are used to represent the quantity or count of objects. They indicate "how many" of something there are. For example, the numbers 1, 2, 3, 4, and so on are cardinal numbers. They are the basic numbers used for counting and performing arithmetic operations like addition and subtraction. Cardinal numbers are the ones we use in everyday situations to quantify things, such as "three apples," "five dogs," or "ten books." Ordinal Numbers: Ordinal numbers, on the other hand, are used to indicate the position, order, or rank of an object in a sequence. They represent the "position" or "order" of something, rather than its quantity. For example, the numbers 1st, 2nd, 3rd, 4th, and so on are ordinal numbers. Ordinal numbers are often used to describe things in a sequence, such as "the first place," "the second chapter," or "the third day."
