Listeros,

Scientists have decoded Aztec records showing how the Aztecs measured
tracts of land for taxation. Records from the Aztec city of
Tepetlaoztoc record each household and amount of land owned for tax
purposes. Codices from 1540-44 survive from that city. Five
algorithims were used using hearts, hands, and arrows for measuring
fractions. The records are meticulous and well organized.
