Sure, I can explain ordinals in a simple way. Ordinals are used to describe the order or rank of something. For example, if there are three people in a race, we can use ordinals to describe their finishing positions. The first person to cross the finish line would be in 1st place, the second person would be in 2nd place, and the third person would be in 3rd place.

In general, we use ordinals to describe the position of something in a sequence or a list. We use words like first, second, third, fourth, and so on to indicate the position. I hope that helps!
