Ordinal numbers are used every day in our daily lives. We don’t even realise this. It is therefore essential that students learn these concepts in a way that they can remember them. Ordinal numbers are also referred to as ranking numbers. Ordinal numbers always represent the rank or position. Ordinal numbers are written using ‘st’, ‘nd’, ‘rd’, and ‘th’ as superscripts with the numbers. For example, 1 st tells us that the object at number 1 is actually first in the position.
Ordinal Number Names
Ordinal number names are always written using the suffix st (first), nd (second), third (rd) for numbers ending in 1, 2 and 3. For the rest of the numbers ‘th’ is used as a suffix. For example : fourth, fifth, tenth, eleventh, etc. For example, we express 51 as fifty – first, 52 as fifty – second, and 53 as fifty – third.
Cardinal Numbers
Cardinal numbers are the counting numbers which represent the number of objects or people. Cardinal numbers show quantity. Example : There are eight apples in the basket, Cage contains two beautiful birds.
