新GRE考试实施以来，数学部分的考试难度也有所增加，但是大家还是要在在新GRE数学复习时把基础打牢。如果新版GRE数学基本考点都没有复习到，如何能拿到分数呢?

**Set**

A set is a collection of objects or things. Each object in a set a member or element of that set.Size of a set is the number of members in the set.

Example:

The set of even numbers between 2 and 10 is of size 5:{2,4,6,8,10}.

The set of primes between 2 and 10 is of size 4:{2,3,5,7}.

Remember:

Each member of set A belongs to A or is in the set A.

A set can not have repeating member:{1,3,1,2}is not a set.

Rearranging the order of the members does not change the set:{1,2,3}is same as{3,2,1}.
