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(méi)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)。祝大家都能取得理想成績(jī)!
