What are some examples of cardinality in mathematics?
Cardinality refers to the number of elements in a set. For example, the set {1, 2, 3} has a cardinality of 3.
Can you give me an example of a finite set?
Sure! The set of days in a week, {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}, has a cardinality of 7.
What about an infinite set?
An example of an infinite set is the set of all natural numbers, {1, 2, 3, ...}, which has an infinite cardinality.
How do we compare the cardinality of two sets?
To compare cardinalities, we can use one-to-one correspondence. If we can pair every element of one set with exactly one element of another, they have the same cardinality.
