新GRE數學復習要點:Term

　　新gre數學的難度相當于高中數學水平，只要大家認真復習，在新gre數學考試中拿高分甚至拿滿分都是很有可能的。不過大家也不能忽略新gre數學中可能會出現的考點難點。下面，為大家整理新GRE數學復習要點:Term，希望對大家有所幫助。

　　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.

　　應對gre數學考試的時候，考生不要過于緊張，把基本概念弄明白，再記住一些新版gre數學必備的詞匯，那么相信新版gre數學應該沒有問題。
