數學的複習是我們GMAT考試的重點，我們複習GMAT數學的時候要重點關注我們的'基礎。基礎對於數學來說實在是太重要了，GMAT入門的同學如何準備數學呢?小編這就給大家分享一下：
一.整數：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=sible adj.可以被整除的 multiple n.倍數
2.商和餘數：quotients and remainders
餘數和商都可以為0
3.奇數和偶數：odd and even integers
奇數和偶數都可以是負數;零一定是偶數
4.質數和合數：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= .
