今天针对新gre数学复习,小编给大家整理的是关于Distributive Law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gre数学难的困境。
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.
俗话说:工欲善其事必先利其器。有一部分考生认为新GRE数学具有一定的难度,这其中的原因是由于考生在复习时没有把新gre数学的基础打牢。想要新gre数学考好,复习的时候一定要把基本概念和重要考点都弄扎实。
