People often confuse ordinal numbers with cardinal numbers and that is why it is necessary to understand the difference between both numbers as well as understand where cardinal numbers are important and where ordinal numbers are important.

## Cardinal Numbers

Cardinal numbers tell us the exact quantity of anything. In simple words, if you look at any object and have a question, "How many?", the answer will be in cardinal numbers. For example, let's say you have five marbles, the value five will be the cardinal number because you are telling the quantity of the object (which is the marble in this scenario).

## Ordinal Numbers

Ordinal numbers are the opposite of cardinal numbers. Cardinal numbers describe the quantity of the object, on the other hand, ordinal numbers tell the position of the object. For example, you parked a car in the parking lot. When you came back, you see four more cars in the same row where you parked your car. Now you will try to remember the position of the car. Let's say you parked the car in the fifth row, hence the value fifth is the ordinal number, and the value four is the cardinal number. A few more examples, fourth year, first floor, tenth color, four-hundredth row, etc.
