GRE數(shù)學(xué)考點《Distributive Law》舉例分析
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.
俗話說:工欲善其事必先利其器。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)的時候一定要把基本概念和重要考點都弄扎實。
