新gre數(shù)學(xué)重要考點(diǎn)：Total Members.

　　2011新gre考試實(shí)施以來(lái)，不僅對(duì)寫(xiě)作部分茫然不知所措，就連我們所擅長(zhǎng)的數(shù)學(xué)也甚是擔(dān)憂，相信這其中的原因還是由于考生在新gre數(shù)學(xué)復(fù)習(xí)時(shí)沒(méi)有把基礎(chǔ)打牢。如果新版gre數(shù)學(xué)基本考點(diǎn)都沒(méi)有復(fù)習(xí)到，如何能拿到分?jǐn)?shù)呢?所以說(shuō)，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)。

　　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.獲得更多gre考試咨詢(xún)點(diǎn)擊進(jìn)入>>>>澳際免費(fèi)咨詢(xún)顧問(wèn)或聯(lián)系QQ客服：

　　由于美國(guó)數(shù)學(xué)基礎(chǔ)教育的難度增加導(dǎo)致數(shù)學(xué)考試越來(lái)越難，但新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(guò)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(méi)有問(wèn)題。
