摘要:GRE数学中涉及到的考点众多,许多概念大家可能中学时学过,但因为长期不接触已经有所遗忘,加之GRE数学真题是以英文表述,因此还需要回炉重造才能应对考试。本文将为大家讲解集合考点相关内容。

虽然中国考生的基础教育,特别是在数学部分,在全世界范围内都是数一数二的,所以对于中国GRE考生来说,GRE数学部分与其他项目相比也相对比较低。但是如果备考GRE的同学对GRE数学部分掉以轻心,很有可能造成失分悲剧。小站为备考GRE的同学们找到了英文原版GRE教程,希望对同学们有所帮助。

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}.

通过以上你的讲解和示例,希望能够帮助备考GRE的同学梳理数学基本概念,夯实基础。在GRE考试中的强项数学部分一举夺魁!
