Cardinal and ordinal numbers

CARDINAL AND ORDINAL NUMBERS
Ordinal Numbers
Ordinal numbers are the numbers that talk about the position of objects. For example, 'The cookies are kept in the 3^rd drawer from the top', 'The orange dress is the 7^th one from the right', 'The soccer ball is kept in the 3^rd carton from the left'. All these sentences have one thing in common - they talk about the positions of the objects. This is the main element in the discussion of ordinal numbers.
What are Ordinal Numbers?
An ordinal number is a number that indicates the position or order of something in relation to other numbers, like, first, second, third, and so on. This order or sequence may be according to the size, importance, or any chronology. Let us understand the ordinal numbers with an example. Ten students participated in a contest. Out of them, the top winners were given medals and were ranked as 1^st, 2^nd, and 3^rd. In this case, the positions: 1^st, 2^nd, and 3^rd are ordinal numbers.
Difference Between Cardinal and Ordinal Numbers
A cardinal number is a number that denotes the count of any object. Any natural number such as 1, 2, 3, etc., is referred to as a cardinal number, whereas, an ordinal number is a number that denotes the position or place of an object. For example, 1^st, 2^nd, 3^rd, 4^th, 5^th, etc. Now, if we say, 'There are 3 ants and 5 bears'. This is an example of cardinal numbers. However, if we say, 'The position of the runners in the running event is first, second, third, and so on', this represents ordinal numbers. Observe the table given below to note the difference between cardinal numbers and ordinal numbers.

List of Ordinal Numbers from 1 to 100
The list of ordinal numbers from 1 to 100 can be learned easily and is quite helpful for specifying the order of any given object. You can use the combinations from this list to find out the ordinal numbers from 100 onward. Observe the table given below in order to understand how ordinal numbers are written. You might be able to pick up a pattern after referring to the first twenty ordinal numbers.

Ordinal numbers are the numbers that indicate the exact position of something or someone at a place. If the number of objects/persons are specified in a list: the position of the objects/persons is defined by ordinal numbers. The adjective terms which are used to denote the order of something/someone are 1st – First, 2nd-Second, 3rd-Third, 4th-Fourth, 5th-Fifth, 6th-Sixth, and so on. All these terms represent the ordinal numbers. Whereas the counting numbers are called cardinal numbers, such as 0, 1, 2, 3, 4, 5, etc.
