content: This handheld electronic calculator has a black and charcoal case and an array of eighteen black, white, and red "Klixon" keys. Such keys have a design trademarked by Texas Instruments and make a distinctive click when pressed. In addition to ten digit keys and one decimal point key, the calculator has four keys for arithmetic functions. One serves as a total key for addition and another as a difference key for subtraction. The top of the keyboard has a constant switch, a D key for recalling the display, a clear entry key, and a red clear key. The on/off switch is behind the clear key and the eight-digit red LED display behind this. A cord for recharging the battery attaches at the back of the top (this example has no cord).
