Texcocan-Aztec peoples in the Valley of Mexico used both picture symbols and lines and dots for numerical notation. Decipherment and analysis of mid-16th-century native pictorial land documents from the Texcocan region indicate that the line-and-dot system incorporated a symbol for zero and used position to ascribe values. Positional line-and-dot notation was used to record areas of agricultural fields, and analysis of the documentary data suggests that areas were calculated arithmetically… Expand
Aztec Arithmetic Revisited: Land-Area Algorithms and Acolhua Congruence Arithmetic
TLDR
Evidence for the use of congruence principles is discovered based on proportions between the standard linear Acolhua measure and their units of shorter length, long an issue in understanding Aztec metrology. Expand
Mathematical accuracy of Aztec land surveys assessed from records in the Codex Vergara
TLDR
Here the accuracy of their area values using modern mathematics compares well with reported errors by Western surveyors that postdate Aztec–Acolhua work by several centuries. Expand
