俗話說：“工欲善其事必先利其器”。很多參加了新版gre考試的同學(xué)都覺得數(shù)學(xué)有點(diǎn)難度，相信這其中的原因還是由于考生在新版gre數(shù)學(xué)復(fù)習(xí)時(shí)沒有把基礎(chǔ)打牢。如果新版gre數(shù)學(xué)基本考點(diǎn)都沒有復(fù)習(xí)到，如何能拿到分?jǐn)?shù)呢?所以說，想要新版gre數(shù)學(xué)考好，復(fù)習(xí)的時(shí)候一定要把基本概念和重要考點(diǎn)都弄扎實(shí)。
今天針對(duì)新版gre數(shù)學(xué)復(fù)習(xí)，小編給大家整理的是關(guān)于Total Members的相關(guān)內(nèi)容，這些概念在考試中一定會(huì)考到的。希望考生能再接再厲，取得一個(gè)好成績(jī)，突破新版gre數(shù)學(xué)難的困境。
新版gre數(shù)學(xué)復(fù)習(xí)重要考點(diǎn)：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.
Remember:
This is a relation between five numbers, and any one can be calculated given the other four.
很多新版gre數(shù)學(xué)復(fù)習(xí)考點(diǎn)都是高中時(shí)候?qū)W到的知識(shí)點(diǎn)，考生不要過于緊張，把基本概念弄明白，再記住一些新版gre數(shù)學(xué)必備的詞匯，那么相信新版gre數(shù)學(xué)應(yīng)該沒有問題。
