A first processing section performs calculation functions based on input from the numeral keys and the function keys and displays the result on the display. A second processing section performs a time keeping function based on values programmed by user via the numeral keys and function keys, and displays a total elapsed or remaining time, a current exam problem, and an elapsed or remaining time for the current exam problem on the display. A switch within the calculator forwards the signal from the numeral keys to either the first or second processing section based on a switching state which is controlled by a switch key on the housing or one of the function keys.
