  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}.

  俗话说:“工欲善其事必先利其器”。有一部分考生认为新GRE数学具有一定的难度,这其中的原因是由于考生在复习时没有把新gre数学的基础打牢。想要新gre数学考好,复习的时候一定要把基本概念和重要考点都弄扎实。
