2011新gre考試實施以來，不僅對寫作部分茫然不知所措，就連我們所擅長的數(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)時沒有把基礎(chǔ)打牢。如果新版gre數(shù)學(xué)基本考點都沒有復(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)的時候一定要把基本概念和重要考點都弄扎實。
Intersection of Sets
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.
union of Sets
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 .
由于美國數(shù)學(xué)基礎(chǔ)教育的難度增加導(dǎo)致數(shù)學(xué)考試越來越難，但新gre數(shù)學(xué)復(fù)習(xí)考點都是高中時候?qū)W到的知識點，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。
