很多同学做完GRE数学都自信满满，觉得自己这次数学满分稳啦。但，现实总是异常骨感……
中国学生在GRE数学其中一大丢分原因就是题读不对，那么今天我们就来盘点一些GRE数学中令中国学生迷惑的表达吧~
|x-7|≤3, |y-2|≤10. What is the least possible value of y-x?
答案-18
|x-7|≤3, |y-2|≤10. y-x的最小值是多少?
正确理解：A is divided by B是前面除以后面，即A÷B
When positive integer m is divided by 6, the remainder is 4. When positive integer p is divided by 6, the remainder is 5. What is the remainder when the product mp is divided by 6?
答案：B
正整数m除以6，余数是4。正整数p除以6，余数是5。mp的乘积除以6余多少？
根据“正整数m除以6，余数是4”我们可知m=6a+4
因此mp=（6a+4）（6b+5）=36ab+30a+24b+20，因为未知数前面的系数都能整除6，因此不会产生除以6的余数，这个式子除以6的余数取决于20除以6的余数，即2，所以选B。
03 two times as many A as B
There are three kinds of balls, red, blue and green, there are 4 times as many red balls as green balls, and 3 times as many red balls as blue balls. If the number of green balls is an positive even, and the number of blue balls is at least one. What is the least number of red balls?
有三种类型的球：红色，蓝色和绿色。红色的球是绿色球的4倍，红色的球是蓝色球的3倍。如果绿色球的数量是一个正偶数，并且至少一颗蓝色的球。红色球最少多少颗？
根据“红色的球是绿色球的4倍”和“绿色球的数量是一个正偶数”这2个条件，我们知道红色的球是4*2即8的倍数；“红色的球是蓝色球的3倍”和“至少一颗蓝色的球” 这2个条件，我们知道红色的球是3的倍数。根据红色的球即是8的倍数和3的倍数，我们知道红色的球是24的倍数，因此最少是24颗。
04 A is two times greater than B
非常多同学受到我们中文习惯的影响误以为“A is two times greater than B ”表达的是“A是B的3倍”
