This handheld electronic calculator has a white and black plastic case with twenty rounded rectangular plastic keys. In addition to ten digit keys, a decimal point key, four arithmetic function keys, a total key, a percentage key, and a clear key, the calculator has two blank keys that appear to have no function. Just above the keyboard, on the left, is the on/off switch. Behind this is an eight-digit red LED display. A mark on the display cover reads: Mathmatic S-888.
The back of the calculator has a battery compartment at the top that is missing its cover. A sticker below this is marked: MODEL S-888. It gives examples of working the calculator. Further text at the bottom reads: MATHMATIC SALES, INC., WATERBURY, (/) CONNECTICUT 06704 (/) made in Thailand.
