Abstract:
1. An electronic device comprising: a display device configured to detect a contact position; a storage in which data is stored, a touch manipulation mode and operational processing being correlated with each other in the data; and a processor that causes the display device to display a mathematical formula, determines the touch manipulation mode detected by the display device, reads the operational processing corresponding to the determined touch manipulation mode from the storage, performs the operational processing on the mathematical formula displayed on the display device, and causes the display device to display a mathematical formula of result of the performed operational processing, wherein the determined touch manipulation mode includes a mode corresponding to two-point touch manipulation performed on the display device by a user, and wherein, in the storage, the touch manipulation modes which serve as a pair of modes opposite to each other are correlated to the pieces of operational processing which serve as pathways opposite to each other in the data in which the touch manipulation mode and the operational processing are correlated.
