Individual mathematicians often have their own way of pronouncing mathematical expressions and in many cases there is no generally accepted \correct" pronunciation.

Distinctions made in writing are often not made explicit in speech; thus the sounds fx may

be interpreted as any of: fx, f(x), fx, FX, FX, ! FX . The di?rence is usually made clear

by the context; it is only when confusion may occur, or where he/she wishes to emphasise

the point, that the mathematician will use the longer forms: f multiplied by x, the function

f of x, f subscript x, line FX, the length of the segment FX, vector FX.

Similarly, a mathematician is unlikely to make any distinction in speech (except sometimes

a di?rence in intonation or length of pauses) between pairs such as the following: x + (y + z) and (x + y) + z

pax + b and pax + b

an ?1 and an?

*几个GRE最常用的概念: 偶数(even number>:能被2整除的整数; 奇数(odd number>:不能被2整除的数; 质数(prime number>:大于1的整数,除了1和它本身外,不能被其他正整数所整除的,称为质数。也叫素数;<学过数论的同学请注意,这里的质数概念不同于数论中的概念,GRE里的质数不包括负整数)b5E2RGbCAP 倒数(reciprocal>:一个不为零的数为x,则它的倒数为1/x。 *最重要的性质: 奇偶性:偶加偶为偶,偶减偶为偶,偶乘偶为偶; 奇加奇为偶,奇减奇为偶,奇乘奇为奇; 奇加偶为偶,奇减偶为偶,奇乘偶为偶。 等差数列 GRE数学中绝大部分是等差数列,,形式主要为应用题。题目会说三年稳步增长第一年的产量是x,第三年的产量是y,问你的二年的产量。 p1EanqFDPw 数理统计 *众数(mode> 一组数中出现频率最高的一个或几个数。 例:mode of 1,1,1,2,3,0,0,0,5 is 1 and 0。 *值域(range> 一组数中最大和最小数之差。 例:range of 1,1,2,3,5 is 5-1=4 *平均数(mean)算术平均数对一组数进行排序后,正中间的一个数<数字个数为奇数),或者中间两个数的平均数<数字个数为偶数)。例: median of 1,7,4,9,2,5,8 is 5 median of 1,7,4,9,2,5 is (5+7>/2=6DXDiTa9E3d ps: GRE经常考察众数与数的个数的积和这组数的和的大小。 *标准偏差(standard error>一组数中,每个数与平均数的差的绝对值之和,再除以这组数的个数n 例:standard error of 0,2,5,7,6 is: (|0-4|+|2-4|+|5-4|+|7-4|+|6- 4|>/5=2.4RTCrpUDGiT *standard variation<方差) 一组数中,每个数与平均数之差的平方和,再除以这组数的个数n5PCzVD7HxA 例: standard variation of 0,2,5,7,6 is: _ 2 2 2 2 2_ |_(0-4> +(2-4>+(5-4>+(7-4>+(6-4>_|/5=6.8jLBHrnAILg *标准差(standard deviation>
