Administrative quipus are characterized by pendant cords with tiers of knots separated by spaces that indicate decimal values—what we would understand as the individual columns of digits in a numbering system, such as units (1 through 9), tens, hundreds, and thousands. The twist direction of the cords is almost always Z-spun and S-plied. The Inca used three main knots to signify numerical values: figure-eight knots, long knots, and single knots. Each knot type signified a different unit of measurement. Cord color also had significance; however, its meaning is at present unknown. This administrative quipu, which consists of three different quipus attached along the primary cord, was used to record statistical information, such as taxes, census data, and storehouse inventories. The plain white, reddish-brown, and tan cords on the right are blanks for future use. #hhm⠀
