State The Number Of Members Of The Set

If A is a set then the number of members of set A is written with notation n(A). In this case n(A) is called a cardinal number of A, which is a number that states the number of members of set A.

The set with the number of finite members is called a finite set, while the set with many infinite members is called an infinite set.

For example A is a natural number, the members are 1, 2, 3, ... many members of set A are infinite, written n(A) = infinite.

So many articles this time. Sorry if there is a mistake.
Final words wassalamualaikum wr. wb.
