Abstract
A display system for a compact electronic apparatus uses a multi-level display means with a plurality of display lines. When the result of a computation is not displayed, all these display lines are available for displaying a computation expression. When the result of a computation is desired, that portion of the expression on the line on which the result of the computation is displayed is cleared. As a result, the user may be able to see the entire expression at a single glance and distinction between the expression and the result of the computation is clear so as to prevent misrecognition by the user.
