Abstract

PURPOSE:To obtain plural operation results at a time, by depressing an operation designating key to execute repeatedly the operation based on data inputted by entry keys and a designated operation expression plural times. CONSTITUTION:After an expression mode key is depressed, entry keys 4, operation keys 5, alphabetic keys 7, and designating keys 8 are used to input an algebraic expression, and this expression is displayed on an expression display part 3. Next, after a data designating key 9 is depressed, alphabetic keys 7, entry keys 4, and operation keys 5 are used to input data to be substituted. Inputted data A1-A3 are displayed in display positions a1-a3 of an input data part A. When a calculation command key 10 is depressed, the operation of the inputted algebraic expression is executed, and operation results B1-B3 are displayed in display positions b1-b3 of an operation value part B. Thus, the calculation command key 10 is depressed once to repeat the operation based on the same algebraic expression in accordance with input data, and plural operation results are obtained.
