新版gre数学复习重要考点:Distributive Law
Like real number, when multiplying a sum or difference of terms, the distributive property of multiplication allows us to distribute the multiplying term among the terms being added or subtracted.
Example:
3=32x+3y,
3a=3a2x+3ay,
3x=3x2x+3xy.
=2x+y=3x2x+42x+3xy+4y.
Remember:
Do not forget to multiply all the terms inside the parenthesis.
For division, the sum and difference in the numerator can be distributed:/=x/+y/.
For division, the sum and difference in the denominator cannot be distributed ://2x+/y.
很多新版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。
