Abstract:
1. An electronic calculator, comprising: a display device; a storage having an operator priority table in which an operator operation priority is stored; and a processor that performs: causing the display device to display a formula; performing sequentially an operation of each formula element constituting the formula displayed on the display device according to the operator priority table; displaying distinctly the formula element, to which the operation is performed in the formula displayed on the display device, on the display device each time each formula element operation is sequentially performed; displaying a solution corresponding to the formula element to which the operation is performed on the display device each time each formula element operation is sequentially performed; displaying distinctly the formula element to which a current operation is performed on the display device in a mode that is different from that of the formula element to which the operation is already performed, when the solution obtained by the last formula element operation is different from the solution obtained by the current formula element operation while remaining without disappearing by current operation processing; and displaying the solution corresponding to the formula element to which the current operation is performed on the display device independently of the solution obtained by the last formula element operation, wherein the solution obtained by the last formula element operation is different from the solution obtained by the current formula element operation while remaining without disappearing by the current operation processing.
