In a method for presenting information, an interactive document, for example, may be created that includes both an input expression and a result generated by evaluating the input expression, and where the input expression can be selectively hidden. This may permit “decluttering” of the document so that it may be easier to follow. At the same time, user interface mechanisms allow a viewer to reveal the input expression if the viewer desires to see the input expression. In this method, an input expression and a result corresponding to an evaluation of the input expression are presented on a workspace associated with a computational software application. Additionally, a first user interface mechanism associated with the input expression is presented on the workspace. In response to an activation of the first user interface mechanism, the input expression may be hidden on the workspace, while the result is presented on the workspace.
