字號(hào):


    新GRE數(shù)學(xué)考試的考點(diǎn)都是高中時(shí)候?qū)W到的知識(shí)點(diǎn),考生不要過于緊張,把基本概念弄明白,再記住一些新GRE數(shù)學(xué)必備的詞匯,那么相信新GRE數(shù)學(xué)應(yīng)該沒有問題。
    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.
    有一部分考生認(rèn)為新GRE數(shù)學(xué)具有一定的難度,這其中的原因是由于考生在復(fù)習(xí)時(shí)沒有把新GRE數(shù)學(xué)的基礎(chǔ)打牢。想要新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)!
