Def. Set. Any collection of objects.

No restriction is placed on the nature of the objects in a set. They can be anything: points, lines, numbers, people, countries, etc. Thus the mathematical meaning of the word set is the same as the regular, nontechnical meaning of the word.
Cardinal number of a set. Two sets are said to have the same cardinal number if and only if they can be put into one-to-one correspondence i.e. if and only if they are equivalent.
A set A is said to have the cardinal number n if and only if there exists a one-to-one correspondence between the elements of A and the natural numbers 1, 2, 3, .... , n.

Synonyms. The cardinal number of a set is also called the potency of the set or power of the set.

cardinality of a set

Explanation:

Cardinalul unei multimi este numarul elementelor acelei multimi.
Exemplu:
M = {1;2;3;5;7}. Cardinalul multimii M este 5 (multimea M are cinci elemente).

In mathematics, the cardinality of a set is a measure of the "number of elements of the set". For example, the set A = {2, 4, 6} contains 3 elements, and therefore A has a cardinality of 3.
