今天针对新gre数学复习,gre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gre数学难的困境。
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.
俗话说:工欲善其事必先利其器。有一部分考生认为新GRE数学具有一定的难度,这其中的原因是由于考生在复习时没有把新gre数学的基础打牢。想要新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。
