The Incas came from South America and used different coloured strings to count. There were between seven and two thousand strings on the quipu. Different knots signified different units such as 1, 10 or 100 etc. The colours signified what was being counted. There was a central rope and strings came off it. The Incas seemed to be very talented at tying knots.
