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. |
