What is the Quipu number system used by the Inca?

Explanation:
The Inca used a system of knotted strings called a quipu to keep numerical records and store information. A main cord carried many pendant cords, and the knots on those cords represent digits. The type of knot and its position along the cord convey numbers and place value, so you could track quantities like goods, tribute, or census data by reading the pattern of knots. Colors and groupings of cords could indicate categories or different data sets. This method is a hands-on, non-written way of recording information, unlike parchment, clay tablets, or any kind of binary marks on sticks.
