新GRE数学考试的其中一个考点是交集和并集,为了帮助考生能够更好的掌握这个GRE数学的重要考点,下面澳际教育小编就给大家详细的讲解一下这个新GRE数学考试的考点。   对于数学中的并集和交集,我们并不陌生,在GRE数学考试中,也有这一考查内容。本文澳际教育GRE考试频道为大家介绍的是GRE数学复习考点“并集和交集”。   新GRE数学复习重要考点:Intersection of Sets交集   Intersection of two sets is another set with only the members that are in both sets. If the two sets do not share any common member, the intersection is the empty set with no member.   Example:   Intersection of {1,2,3} and {2,3,5} is the set {2,3}.   Intersection of the set with all primes and the set with all even numbers is the set {2} since only 2 is both even and prime.   Intersection of {1,2,3} and {4,5,6} is the empty set {}.   Remember:   Intersection contains only the common members.   Two sets are disjoint if they have no member in common, that is they have an empty intersection.   新GRE数学复习重要考点:Union of Sets 并集   Union of two sets is another set with all the members from both sets.   Example:   Union of {2,3,5} and {1,3,4} is the set {1,2,3,4,5}.   Union of {1,2,1} and {1,2} is the set {1,2,1}.   Remember:   The common members do not repeat in the union.   本文针对新GRE数学考试的交集和并集考点进行了详细的解析,考生在复习新GRE数学考试的时候,可以通过本文掌握这个考点,希望能够对大家的GRE数学考试有所帮助。   澳际六步曲第二步为您进行考试指导,澳际培训核心思维颠覆国内传统大班无差异化批发模式,采取一对一个性化教学,辅之小班精英辅导应试方法和学生英语能力结合,考试辅导和留学规划一体化行动,学生国际化英语思维构建及西方人文知识和视野的开拓并重。   我们具体的服务项目如下:   1. 免费测评模考,分析申请人的问题,制作考试测评报告和备考指导   2. 结合申请人的申请目标和考试基础,制定考试整体规划及时间安排   3. 提供对申请人有帮助的考试经验和机经等   4. 根据需要提供免费口语模拟和指导服务   5. 免费修改作文4篇   6. 考前心理指导,调整考前心理状态   (注:口语模拟和作文修改服务提供时间为每年2月28日-8月1日)
