**What Are Cardinal Numbers?** -
Cardinal numbers are generally referred to as counting numbers. Or to put it simply, the numbers that are used for counting are known as cardinal numbers. Cardinal numbers can help us identify how many of something is there, such as two, four, or five. Suppose you are asked to count the baseballs, footballs, soccer balls and tennis balls that were given to you in a line. This gives you the quick ability to point out the exact ball you are referring to.
Cardinal numbers start from 1. Fractions and decimals are not classified as cardinal numbers as they represent a part of a group. Cardinal numbers tell us about the cardinality of certain groups or sets of objects that means it shows how many objects are there in a set or group.
ORDINAL AND NOMINAL NUMBERS - Other kinds of numbers are often confused with cardinal numbers. These are ordinal and nominal numbers.
Nominal numbers name something. They are used to identify something and do not define the rank or quantity of something - for example, zip code 033242, jersey number 45.
Ordinal numbers show the position of something mentioned in the list. For example, words like second, third, fourth, etc.
