2011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),小編給大家整理的是關(guān)于Adding Monomials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。
Adding Monomials
To add two monomials of the same variables just add the coefficients.
Only two like monomials can be added together.
Example:
By adding 3x and 4x, we get (3+4)x=7x.
By adding 3xy+2xy, we get (3+2)xy=5xy.
By adding as and bx, we get ax+bx=(a+b)x.
Remember:
Monomials can be added only if they have the same variables with identical powers.
由于美國數(shù)學(xué)基礎(chǔ)教育的難度增加導(dǎo)致數(shù)學(xué)考試越來越難,但新gre數(shù)學(xué)復(fù)習(xí)考點(diǎn)都是高中時(shí)候?qū)W到的知識點(diǎn),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。
