【摘要】 即将参加雅思考试的考生们,考试即将到来,你们的备考工作进行得如何了?考必过为大家精心整理了GRE数学重要知识点:Distributive Law,希望能够帮助大家通过雅思考试。那么,同学们一起快来做题吧!关于GRE数学重要知识点:Distributive Law的具体内容如下:
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.
以上就是考必过为大家整理的GRE数学重要知识点:Distributive Law的具体内容,你全部做对了吗?所谓未来,其实只是过去的堆砌,堆砌昨天便有了今天,堆砌今天便有了明天,堆砌明天便是未来。最后,考必过预祝大家在未来的雅思考试中能够取得优异的成绩!
