This handheld electronic calculator has a case in two shades of brown and an array of twenty-three rectangular plastic keys. These include ten digit keys, a decimal point key, a total key, and four arithmetic function keys. The leftmost column of keys includes %, square root, clear, and clear entry keys. The on/off switch is at the top of the keyboard, next to three memory keys. Behind this is an eight-digit vacuum fluorescent display. A mark above this reads: Radio Shack.
