notes: label: Description
content: This notched band adder has a wooden framework. Six paper bands move in six columns, showing the result in six windows. A paper sheet glued to the front has numerals and the name of the device, as well as cutouts to create the columns. A sheet glued to the back gives instructions. The columns widen at the top for carrying in addition and at the bottom for borrowing in subtraction. The object came to the Smithsonian from the collection of Felt and Tarrant Manufacturing Company. The date assigned is quite arbitrary.
