俗話說:“工欲善其事必先利其器”。很多參加了新版gre考試的同學(xué)都覺得數(shù)學(xué)有點難度,相信這其中的原因還是由于考生在新版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。
今天針對新版gre數(shù)學(xué)復(fù)習(xí),小編給大家整理的是關(guān)于Term的相關(guān)內(nèi)容,這些概念在考試中一定會考到的。希望考生能再接再厲,取得一個好成績,突破新版gre數(shù)學(xué)難的困境。
新版gre數(shù)學(xué)復(fù)習(xí)重要考點: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.
很多新版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。
