Nominal numbers are numbers that are used to represent something in order to make them more unique. We can say nominal numbers are used as names so that something can easily be understood. When these numbers are used, they might seem irrelevant, but they hold very vital information about whatever they are used for. Your phone number is an example of a nominal number.

Also, the number written on the Jersey of an athlete or a player is also a number. At times, a nominal number can consist of numbers and alphabets. On the other hand, an ordinal number is used to reveal the position, rank of an object within a set.

Most times, ordinal numbers are represented with words such as first, second, third, tenth. Ordinal numbers are used mostly to give certain information about our actual age. For example I will be celebrating my 30th birthday tomorrow.
