Distributive Law

GRE數學考點《Distributive Law》舉例分析

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.

俗話説:工欲善其事必先利其器。有一部分考生認為新GRE數學具有一定的難度,這其中的原因是由於考生在複習時沒有把新gre數學的'基礎打牢。想要新gre數學考好,複習的時候一定要把基本概念和重要考點都弄紮實。
