俗话说：工欲善其事必先利其器。很多参加了新版gre考试的同学都觉得数学有点难度，相信这其中的原因还是由于考生在新版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。

　　今天针对新版gre数学复习，小编给大家整理的是关于Term的相关内容，这些概念在考试中一定会考到的。希望考生能再接再厉，取得一个好成绩，突破新版gre数学难的困境。

　　新版gre数学复习重要考点：Term

　　A product of coefficients and any number of variables with exponents is called a term. Terms that have the same variables with identical exponents for each variables are called like terms.

　　Example:

　　3x,axy,4x2yz are terms. 3x+2 is not term: it is a sum of two terms.

　　3x2y and 7x2y are like terms since both have the same variables x and y with identical exponents: 2 for x and 1 for y.

　　Remember:

　　There cannot be any addition or subtraction in a single term.

　　Since multiplication is associative, rearrangements of variables does not change a term:3xy is same as 3yx.

　　3x2y and 7xyx are like terms.
