Materials used to make early abacuses in different regions varied. For example, among the Maya and Aztec people of Mesoamerica, maize kernels threaded on strings were used instead of beads, while the Inca people who lived in Peru centuries ago had an abacus that was made up of a ââ¬Å"tray with compartments that were arranged in rows in which counters were moved in order to make calculationsâ⬠(Keoke and Porterfield 1).
