# Adding expressions

You can add and view expressions in the Expressions view. The Expressions view is part of the Debug perspective.

To add an expression:

1. Click Run > Add Expression.
2. Type the expression that you want to evaluate. For example, (x-5)*3 ).

3. Click OK.

   The expression and its value appear in the Expressions view. When the execution of a program is suspended, all expressions are reevaluated and changed values are highlighted.
