新GRE数学考试要求的是中学的数学知识,考生们对于新GRE数学上面来说还是比较有把握,不过说到具体的GRE数学考点要求就不一定这么清楚。下面就为大家介绍新GRE数学考点及这些GRE数学考点解析,帮助考生们系统的复习一遍新GRE数学,梳理整合新GRE数学考试所需要的知识。
GRE考试数学考点:Adding Monomials
To add two monomials of the same variables just add the coefficients.
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.
