如何打好GMAT數(shù)學(xué)基礎(chǔ)
數(shù)學(xué)的復(fù)習(xí)是我們GMAT考試的重點，我們復(fù)習(xí)GMAT數(shù)學(xué)的時候要重點關(guān)注我們的基礎(chǔ)。基礎(chǔ)對于數(shù)學(xué)來說實在是太重要了，GMAT入門的同學(xué)如何準(zhǔn)備數(shù)學(xué)呢?小編這就給大家分享一下：
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=7 4, 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)
4.質(zhì)數(shù)和合數(shù)：prime numbers and composite numbers
A prime number is a positive integer that has exactly two different positive divisors，1 and itself. For example, 2,3,5,7,11, and 13 are prime numbers, but 15 is not, since 15 has four different positive divisors, 1, 3, 5, and 15. The number 1 is not a prime number, since it has only one positive divisor. Every integer greater than 1 is either prime or can be uniquely expressed as a product of prime factors. For example, 14= , 81= , and 484= .
注:GMAT考試除了1和其本身外,還有其他因子的數(shù)叫合數(shù)。GMAT數(shù)學(xué)最小的質(zhì)數(shù)為2，最小的合數(shù)為4，在討論質(zhì)數(shù)和合數(shù)時，都指正數(shù)。1和0既不是質(zhì)數(shù)，也不是合數(shù)。
5.整數(shù)中的重要概念：
Perfect square完全平方數(shù)，諸如9 = 32
Perfect cube 完全立方數(shù)，諸如8 = 23
the greatest common divisor 最大公約數(shù)
GMAT入門幾個數(shù)所公有的最大因子稱最大公約數(shù)，諸如：48與36的公因子有1，2，3，4，6，12，其中12為最大公約數(shù)。
the least common multiple最小公倍數(shù)
幾個數(shù)所公有的最小倍數(shù)稱最小公倍數(shù)，諸如：3，7和14的最小公倍數(shù)為42。
連續(xù)正整數(shù)的算術(shù)平均值也是首項和末項的算術(shù)平均值。
同理，連續(xù)奇數(shù)與連續(xù)偶數(shù)的算術(shù)平均值也是首項和末項的算術(shù)平均值。
以上就是小編整理的GMAT考試數(shù)學(xué)的復(fù)習(xí)方法，要知道基礎(chǔ)是GMAT數(shù)學(xué)的復(fù)習(xí)重點。所以GMAT入門的同學(xué)我們要努力的打好自己的基礎(chǔ)，這樣我們的考試復(fù)習(xí)才會更加順利。
