Only two like monomials can be added together. Example: By adding 3x and 4x, we get (3+4)x=7x. By adding 3xy+2xy, we get (3+2)xy=5xy. By adding as and bx, we get ax+bx=(a+b)x. Remember: Monomials can be added only if they have the same variables with identical powers. GRE 考试数学考点:Algebraic Expression One or many terms connected by algebraic operations is called an algebraic expression. The operations between the terms must be valid to yield an expression. Example (3x+5),(ax2+c),and (xy+a)(x+y) are all algebraic expressions. (2x+5)+· (3x) is not an expression since + followed by·is not a valid sequence of operations. Remember There is no=sign in an expression. 以上就是新 GRE 数学考点及 GRE 数学考点解析的介绍,希望这些知识点的介绍可以帮助大家复习新 GRE 数学, 为大家复习新 GRE 数学提供条件。希望考生们认真复习新 GRE 数学考试,能够取得自己理想的成绩。新东方在 线论坛也会不断的为大家分享更多有助于考生们复习考试的新 GRE 考试材料及技巧。
