新版gre數(shù)學(xué)復(fù)習(xí)Term部分
新gre考試實(shí)施以來，不僅對寫作部分茫然不知所措，就連我們所擅長的數(shù)學(xué)也甚是擔(dān)憂，相信這其中的原因還是由于考生在新gre數(shù)學(xué)復(fù)習(xí)時(shí)沒有把基礎(chǔ)打牢。如果新版gre數(shù)學(xué)基本考點(diǎn)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(shí)候一定要把基本概念和重要考點(diǎn)都弄扎實(shí)。
今天針對新版gre數(shù)學(xué)復(fù)習(xí)，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(gè)好成績，突破新版gre數(shù)學(xué)難的困境。
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.
