たことを特徴とする演算式入力装置。 In an arithmetic expression input device that has at least a numeric key and a function key, and uses the numeric key and the function key to store an arithmetic expression including variables, a predetermined order in which variables can be used as variables in the arithmetic expression is determined. A storage control means for detecting and storing a previously unused variable among a plurality of variables stored in the memory, an external operation means for changing the variable stored by the storage control means, and an operation performed by the external operation means. and changing means for changing the variable stored by the storage control means to a variable in the next order when the stored variable is stored in the storage control means.
