Abstract
PURPOSE: To use the operation result as an operated number as it is to simplify key input operations, by displaying the operation result and information to be inputted next on a display unit to make understanding of an expression to be calculated possible simultaneously with inputting the operation result together with information to be inputted next into an expression memory part according to the information above.
CONSTITUTION: Key board information and an operand value are supplied from key input device 3 to control part 4, and the operation processing is performed according to the operand value; and after the operation completion, the key code of the operation result is only sent to expression memory circuit 5 as it is but also displayed on display unit 1 through buffer 2 for display. Next, in case that another input is multiplied by this operation result, the operation is executed when the equal key is depressed, and the operation result is not only stored in operation result memory circuit 6 but also displayed on display unit 1. Then, when the operation result is used as an operated number as it is, the operation result is inputted together with information to be inputted next into circuit 6 according to this information, and simultanously, they are displayed on display unit 1, thus facilitating the next key unit operation.
