A rope with knotted cords, which could have been of different lengths and colors, was primarily used as a calculator. This ancient calculation tool was used by Inca, called <em>quipu</em>. It was also used for recording and storing information. Quipu consisted of ropes that were knoted and represented numbers. The smallest number in, for example, the two-digit number 26 would be represented by six touching knots at the free end of the rope, and two touching knots with a distance in relation to the first six would come on top of it on the hung rope.
