# What are Ordinal Numbers?

There are two types of numbers. One is the ordinal number and other is the cardinal number. Students are first taught the concept of cardinal numbers because it is easier to understand. Cardinal numbers are numbers in their original form. For example, one, two, three, four, fifteen, nineteen, twenty-five, ninety-nine, etc. On the other hand, ordinal numbers are the numbers that indicate a position. They are used to represent the order of things or objects. For example, first, second, fourth, ninth, etc.

The main difference between the ordinal numbers and cardinal number is that the ordinal numbers are not used to indicate the quantity like the cardinal numbers. Rather, ordinal numbers indicate the position of a thing or an object's standing. They have specific writing. When you write the ordinal numbers in numerals, you always add two letters with them that is "st", "nd", "rd", and "th". Ordinal numbers have been used in the literature by many writers. Most of the titles of books are written in ordinal numbers, for example, The Second watch, by J.A. Jance and Henry the fourth, by Stuart J. Murphy.

Ordinal numbers have a specific purpose for their use. They show the order of things. With the help of ordinal numbers, one can easily understand positions. Ordinal numbers will tell the exact position of objects and things. They are mostly used in displaying collections. It becomes easier to mark things with the ordinal numbers. Other common uses of ordinal numbers are in mathematics, literature, sciences, and other such fields.
