The people used a decimal counting system and counted with their fingers. Their system went from 1 to 10 and for higher numerations they used the prefix "quihicha" or "qhicha", which means "foot" in their Chibcha language "Muysccubun". Eleven became thus "foot one", twelve "foot two", etc. As in the other pre-Columbian civilizations, the number 20 was special. It was the total number of all body extremities; fingers and toes. The Muisca used two forms to express twenty: "foot ten"; "quihícha ubchihica" or their exclusive word "gueta", derived from "gue", which means "house". Numbers between 20 and 30 were counted "gueta asaqui ata" ("twenty plus one"; 21), "gueta asaqui ubchihica" ("twenty plus ten"; 30). Larger numbers were counted as multiples of twenty; "gue-bosa" ("20 times 2"; 40), "gue-hisca" ("20 times 5"; 100). The Muisca script consisted of hieroglyphs, only used for numerals.
