新gre数学重要考点:Total Members.

刚刚更新 编辑: 浏览次数:96 移动端

  2011新gre考试实施以来,不仅对写作部分茫然不知所措,就连我们所擅长的数学也甚是担忧,相信这其中的原因还是由于考生在新gre数学复习时没有把基础打牢。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?所以说,想要新版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。

  Total Members

  Sometimes there are members that do not belong to either set A or B.In that case the total number of members=Size A+Size B-Number of common members+Number of members not in A or B.

  Example:

  In an office, 35 people drink coffee, 27 drink tea, 12 drink both, and 4 drink neither. The total number of people in the office = 35+27-12+4=54.

  In a class of 40 students, 20 study algebra, 15 study geometry, 8 study both.The total number of students that do not study either=40-(20+15-8)=13.获得更多gre考试咨询点击进入>>>>澳际免费咨询顾问或联系QQ客服:

  Remember:

  This is a relation between five numbers, and any one can be calculated given the other four.

  由于美国数学基础教育的难度增加导致数学考试越来越难,但新gre数学复习考点都是高中时候学到的知识点,考生不要过于紧张,把基本概念弄明白,再记住一些新版gre数学必备的词汇,那么相信新版gre数学应该没有问题。
