CARDINAL NUMBER Meaning and
Definition
-
A cardinal number refers to a number that is used to identify or count the quantity of objects or entities in a set, representing its magnitude or size. It is a fundamental concept in mathematics used for counting and ordering purposes. Cardinal numbers express the notion of how many or in what quantity.
The term "cardinal" comes from the Latin word "cardinalis," which means "important" or "principal." In mathematics, the cardinal numbers are considered the most basic and significant set of numbers. They are also known as "counting numbers" or "natural numbers."
Cardinal numbers are typically represented by Arabic numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and include zero as the starting point. They can be used to describe the size of finite sets, such as the number of apples in a basket or the number of students in a classroom.
In addition to representing quantity, cardinal numbers can also be used in ordinal numbers, which indicate the position or order of an object in a sequence. For example, in the sentence "He is the first student in the line," the word "first" is an ordinal number derived from the cardinal number one.
Overall, cardinal numbers are a fundamental concept in mathematics that allow us to quantify and count objects, providing a standard and universal way of expressing numerical values.
