Abstract: An electronic device includes a display, a memory and a processor being configured to: register a plurality of pieces of first computational data in input order; register at least one or more pieces of second computational data each time the second computational data is input, the at least one or more pieces of second computational data corresponding to the plurality of pieces of first computational data, and each piece of the second computational data including numerical value data and calculation data; when second computational data is registered, determine whether the registered second computational data is consistent with the first computational data in input order corresponding to the registered second computational data; when the registered second computational data is determined to be inconsistent with the first computational data, correct the first computational data; and resume the registration of the second computational data after the first computational data is corrected.
