They don't. The art of using the quipu and reading its meaning has been lost. Researchers have not been able to find anyone who has retained the knowledge, so they have set up a program via computer to analyze and interpret the quipus in their possession. It is a work in progress and they have not fully reported on their results.

The incas used it for keeping records such as, births, deaths, and harvests. Quipus where made out of a group of knotted strings.
The Incas used a record keeping system called knotted strings, known as quipus. Quipus consisted of colored and knotted strings made of different materials that represented numbers, dates, and other information. The knots and colors held different meanings, allowing the Incas to record and communicate important data efficiently. However, much of the information recorded in quipus remains a mystery as the precise system of interpretation has been lost.
The Inca civilization used the terraced system of agriculture to farm on steep mountain slopes. Quipus were knotted strings used by the Inca for record-keeping, with each knot representing a numeric value or information.

The writing system used by the Incas is called Quipus, also referred to as "talking knots." A quipu was colored threads made of llama or alpaca hair, or cotton. A quipu could have up to 2,000cords, and can be compared to a string mop. The quipus may have been attached to wood bases. This system helped the Incas collect and record data, tax records, census records, military organization and calendars.

The Incas had no exact form of mathematics, but they did have a system called quipus used to keep track of things like crops, live stock, number of soldiers, and a number of other things that could be counted. Quipus were coloured strings with knots in them. Different colours and types of knots recorded different things. Only quipus rememberers could interpret what these knots and colours meant - nowadays, no one can tell what they mean.
The best achievement of the Incas was their advanced system of engineering and architecture, including the construction of Machu Picchu. They also had an elaborate communication and administrative system using quipus (knotted cords) to record information. Additionally, the Incas developed innovative agricultural techniques, such as terraced farming, to maximize productivity in the challenging Andean environment.
The Incas used a system of knotted cords called quipus for recording information and keeping records. Each knot, its position, and the color of the cords represented different types of information such as numbers, dates, and events. The quipu served as a form of communication and record-keeping in the Inca Empire.
Stories and songs about the Incas have been passed down through generations via oral tradition. They were also recorded by Spanish conquistadors and missionaries who documented Inca culture during the colonial period. Additionally, archaeological findings and historical records also provide insights into Inca civilization.
