ABSTRACT:
Electronic equipment capable of arithmetic operations displays operands, four function symbols, an "equal" symbol and results in various modes. According to one embodiment, a first operand, a function symbol, a second operand and a result with an "equal" symbol are displayed in the order named on two or three display panels. Alternatively, in order to reduce the power consumption, they may be displayed one at a time on one display panel. According to another embodiment of the present invention, the result of an arithmetic operation, the steps of which are displayed in the manner described above, is added to the contents of a so-called independent memory, and both the result and the new content of the memory may be displayed at the same time. In a further embodiment, the number of arithmetic operations executed may be displayed, and in accordance with a yet further embodiment, a result which overflows a display panel may be displayed on two display panels at the same time.
