Cardinality elementary math
In mathematics, the cardinality of a set is a measure of the number of elements of the set. For example, the set contains 3 elements, and therefore has a cardinality of 3. Beginning in the late 19th century, this concept was generalized to infinite sets, which allows one to distinguish between different types of infinity, and to perform arithmetic on them. There are two approaches to cardinality: one whic… WebSorted by: 3. The cardinality of A relies on two fundamental concepts about all sets: Sets do not contain duplicates, so { x, x } is always the same as { x } Two sets are equal if and only if they contain the same elements. This means that { a, b, c } = { c, b, a } and so on. So while A has been written to look like it contains 4 sets, all 4 of ...
