GRE數(shù)學考點

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*(2x+y)=3*2x+3*y,

3a*(2x+y)=3a*2x+3a*y,

3x*(2x+y)=3x*2x+3x*y.

(3x+4)*(2x+y)=(3x+4)*2x+(3x+4)*y=3x*2x+4*2x+3x*y+4*y.

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)/(2x+y)=x/(2x+y)+y/(2x+y).

For division, the sum and difference in the denominator cannot be.

distributed :(x+y)/(2x+y)≠(x+y)/2x+(x+y)/y.
