Historical claims are tested critically

Continuity, cyclicity and symmetry appear in traditions transmitted through performance and teaching.

It compares long-standing Indigenous practices with the conventional story that begins with Euler's bridges problem.

The study treats drawings as cultural, narrative and mathematical practices rather than extracting patterns from their social meaning.

The paper examines Sanskrit verses and mathematical rationales for corrections that accelerate an infinite series for pi.

Correction terms produced strikingly accurate approximations with fewer terms than the uncorrected alternating series.

Madhava's work predates the European association of the series with Gregory and Leibniz, while later traditions developed in different contexts.

A study dated 10 June 2024 reviews 169 publications and identifies mathematical practices across many societies.

Activities include building, weaving, navigation, games, measurement, patterning and environmental knowledge.

It argues that written theorem-proof traditions should not be the sole standard for recognizing mathematical reasoning.

The authors ask where knowledge is located, who can interpret it and how Indigenous knowledge holders can retain authority.
