Abstract
To provide a computer and a calculation program, allowing confirmation of a calculation history including an intermediate calculation result confirmed during input of a mathematical expression.SOLUTION: The calculator stores operation data including a numerical value and an operator symbol input by a user in a storage unit, displays the input numerical value, the input operator symbol, and a calculation result sequentially calculated based on the input numerical value and operator symbol in a first display area, and displays a mathematical expression based on the input numerical value and operator symbol in a second display area. And a processing unit configured to display, when an operator symbol is selected in the second display area, a numerical value represented by the selected operator symbol in the first display area based on the operation data stored in the storage unit, and display, when an operator symbol is selected in the second display area, a numerical value or a calculation result displayed in the first display area at a time point when the operator symbol is input in the first display area based on the operation data stored in the storage unit.SELECTED DRAWING: Figure 4
