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.
