Maya Independently Develop Zero as a Positional Placeholder

Maya mathematicians in Mesoamerica developed a base-20 positional number system with a dedicated zero symbol, represented by a shell or flower glyph indicating absence. The earliest evidence appears in Long Count calendar inscriptions, including Stela 2 at Chiapa de Corzo dated to 36 BCE. The system possibly originated with the earlier Olmec civilization. This zero enabled complex astronomical and calendrical calculations and developed independently of Old World mathematics. Unlike later mathematical systems, the Maya zero remained primarily for calendrical use rather than general arithmetic operations.
