今天针对新版gre数学复习,小编给大家整理的是关于Evaluating Expressions的相关内容,这些概念在考试中一定会考到的。希望考生能再接再厉,取得一个好成绩,突破新版gre数学难的困境。
新版gre数学复习重要考点:Evaluating Expressions
To evaluate an expression, plug in the specific values for the variables and simplify.
Example
For x=2, the expression 3x+5 evaluates to 32+5=11.
For x=2 and y=1, the expression xy/ evaluates to 21/=2/3.
For x=2, the expression 4yx/ evaluates to 8y/.
Remember
After evaluation the expression does not contain the variable in any form.
