新版gre數學復習Term部分
新gre考試實施以來，不僅對寫作部分茫然不知所措，就連我們所擅長的數學也甚是擔憂，相信這其中的原因還是由于考生在新gre數學復習時沒有把基礎打牢。如果新版gre數學基本考點都沒有復習到，如何能拿到分數呢?所以說，想要新版gre數學考好，復習的時候一定要把基本概念和重要考點都弄扎實。
今天針對新版gre數學復習，給大家整理的`是關于Term的相關內容，這些概念在考試中一定會考到的。希望考生能再接再厲，取得一個好成績，突破新版gre數學難的困境。
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.
