PROBLEM TO BE SOLVED: To overwrite expectation data, to cancel the overwritten expectation data if necessary and to restore an initially set calculation formula. SOLUTION: This device is provided with a calculation means 1 in a spread sheet shape constituted of a cell for storing an optional calculation formula, thus performing various calculations by using it, displaying data to be the calculated result, storing the data by writing optional data and displaying the data, a data write means 2 for writing the data on an optional cell, a calculation formula storage means 3 for storing a prescribed calculation formula, a calculation formula copying means 4 for copying the calculation formula stored in the calculation formula storage means 3 and writing it in the cell at a prescribed position and a cell specifying means 5 for specifying the optional cell. Then, in the case that the cell specified by the cell specifying means 5 is present, the optional data are written on the cell by the data write means 2, and in the case that the cell specified by the cell specifying means 5 is present, the prescribed calculation formula is copied on the cell by the calculation formula copying means 4. |
