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 3*2+5=11.

For x=2 and y=1, the expression xy/(x+y) evaluates to 2*1/(2+1)=2/3.

For x=2, the expression 4yx/(y+x) evaluates to 8y/(y+2).

Remember

After evaluation the expression does not contain the variable in any form.

以上的内容大家一定要好好掌握，在考试的时候发挥出自己应有的水平。
