The chief advantage the Maya and Aztec had over the Inca in managing information is They had writing.
The Maya developed a complex system of hieroglyphic writing, which allowed them to record historical events, religious texts, and administrative information. The Aztecs also had a form of pictorial writing that enabled them to keep records. In contrast, the Inca used a system of knotted strings called quipu for record-keeping, but it was not a form of written language.
