GMAT數(shù)學(xué)復(fù)習(xí)輕松搞定 GMAT數(shù)學(xué)算術(shù)詳解
GMAT數(shù)學(xué)復(fù)習(xí),對于許多準(zhǔn)備參加GMAT考試的考生來說,是一個(gè)艱苦的過程。雖然GMAT數(shù)學(xué)考查的內(nèi)容相當(dāng)于內(nèi)地初中,但是將GMAT數(shù)學(xué)放在英語語境下,讓很多考生很不習(xí)慣,再加上GMAT數(shù)學(xué)強(qiáng)調(diào)的實(shí)際應(yīng)用能力,更為考生增加了難度。作為GMAT數(shù)學(xué)基本功的算術(shù),卻是內(nèi)地考生所熟悉的,就讓專家?guī)湍阒渍?,從算術(shù)上尋找突破口。
一.整數(shù):integer,whole number
1.因子:factor or divisor
If x and y are integers and x0,x is a divisor of y provided that y=xn for some integer n. In this case y is also said to be divisible by x or to be a multiple of x. For example, 7 is a divisor or factor of 28 since 28=74, but 8 is not a divisor of 28 since there is no integer n such that 28=8n.Divisible adj.可以被整除的 multiple n.倍數(shù)
2.商和余數(shù):quotients and remainders
余數(shù)和商都可以為0
3.奇數(shù)和偶數(shù):odd and even integers
奇數(shù)和偶數(shù)都可以是負(fù)數(shù);零一定是偶數(shù)
