有的考生會認為新版gre數學有些難度這是為什么呢?相信應該是備考新版gre數學考試時基礎沒有打牢，基礎沒有夯住做題又何談容易呢。下面是小編為大家搜索總結新版gre數學三個考點：

　　新版gre數學復習重要考點：Set　　

A set is a collection of objects or things. Each object in a set a member or element of that set.Size of a set is the number of members in the set.

　　Example:

　　The set of even numbers between 2 and 10 is of size 5:{2,4,6,8,10}.

　　The set of primes between 2 and 10 is of size 4:{2,3,5,7}.

　　Remember:

　　Each member of set A belongs to A or is in the set A.

　　A set can not have repeating member:{1,3,1,2}is not a set.

　　Rearranging the order of the members does not change the set:{1,2,3}is same as{3,2,1}.

　　新版gre數學復習重要考點：Combinations

　　Number of ways we can select n objects from a group of m distinct objects is m!/!).

　　Example:

　　Number of possible ways to pick 4 oscar nominations from a list of 50 movies is 50!/!)=50!/=50494847/24=230300.

　　Remember:

　　This does not apply if there are identical objects.

　　新版gre數學復習重要考點：Permutation of Objects

　　The number of ways n distinct objects can be ordered is n!.

　　Example:

　　Number of ways 6 people can from a queue is 6!.

　　Number of ways 5 different cars can be parked in 5 parking spaces is 5!.

　　Remember:

　　This does not apply if there are identical objects or ordering does not matter.

　　以上小編給大家分享的備考新版gre數學重要考點，大家可以踴躍補充相互補給;很多新版gre數學復習考點都是高中時候學到的知識點，只要努力相信新版gre數學部分是難不倒我們國內考生的。
