An electronic device includes a display, at least one processor, a memory, and a mind-map user interface stored in the memory, executed by the processor, and configured to create or edit a plurality of topic objects which are formed of user-entered input data and connected to each other in a hierarchical tree structure. The processor is configured to display on the display the plurality of topic objects distributed in the hierarchical tree structure when the mind-map user interface is executed. At least one of the plurality of topic objects contains text string data including numeric data and an arithmetic identifier, and also at least one of the plurality of topic objects contains text string data including a function identifier which indicates a predefined function. The processor is further configured to convert specific text string data, corresponding to the numeric data combined with the arithmetic identifier among the text string data contained in subordinate topic objects connected to a specific topic object having the function identifier, into equivalent numeric string data, and to calculate a result value of the function indicated by the function identifier on the basis of the numeric string data. |
