　　Term A product of coefficients and any number of variables with exponents is called a term. Terms that have the same variables with identical exponents for each variables are called like terms. Example: 3x,axy,4x2yz are terms. 3x 2 is not term: it is a sum of two terms.

　　3x2y and 7x2y are like terms since both have the same variables x and y with identical exponents: 2 for x and 1 for y. Remember: There cannot be any addition or subtraction in a single term. Since multiplication is associative, rearrangements of variables does not change a term:3xy is same as 3yx.
　　3x2y and 7xyx are like terms. 应对gre数学考试的时候，考生不要过于紧张，把基本概念弄明白，再记住一些新版gre数学必备的词汇，那么相信新版gre数学应该没有问题。
