Answer 1

The Incas are credited with creating a system called a khipus to record statistical information. They used a rope and a system of knots to record data such as the number of people living in a community, business exchanges and other accounting information. Each knot represented a specific number or figure, and clumps of knots signified large sums. The khipus is likened to the beginning of the decimal system.
