今天针对新版gre数学复习，小编给大家整理的是关于Subtracting Monomials的相关内容，这些概念在考试中一定会考到的。希望考生能再接再厉，取得一个好成绩，突破新版gre数学难的困境。
Subtracting Monomials
To subtract a monomial from another of the same variables just subtract the coefficients. Only two like monomials can be subtracted from each other.
Example:
By subtracting 3x from 4x, we get (4-3)x=x.
By subtracting 3xy from 2xy, we get (2-3)xy=-xy.
By subtracting bx from ax, we get ax-bx=(a-b)x.
Remember:
Monomials can be subtracted only if they have the same variables with identical powers.
由于美国数学基础教育的难度增加导致数学考试越来越难，但新gre数学复习考点都是高中时候学到的知识点，考生不要过于紧张，把基本概念弄明白，再记住一些新版gre数学必备的词汇，那么相信新版gre数学应该没有问题。
