**What are Ordinal Numbers?**

Ordinal numbers indicate the position or rank of something or someone in a specific order. Unlike cardinal numbers (1, 2, 3, etc.), which indicate quantity, ordinal numbers such as 1st, 2nd, 3rd, etc., represent the position. For instance, “1st” denotes “first,” “2nd” denotes “second,” and so on. These numbers are essential for ranking and ordering items or people.

**Definition and Usage**

Ordinal numbers are used to define the exact position or rank of an item in a sequential list. They are particularly useful in scenarios where the order is important, such as races, queues, or lists. For example, if you have a list of participants in a race, ordinal numbers will indicate who finished 1st, 2nd, 3rd, etc.

**Real-life Examples**

- Ram finished first in his class.
- Sarita was the third girl in line.
- Mohan lives on the fourth floor of his apartment building.
- The table is displayed in the sixteenth position in the store.
