Brahmagupta's rules for zero and negative numbers are highlighted

The paper gathers recent scholarship on Madhava's location, works and place within the Kerala school.

Locating Madhava helps connect texts to teachers, disciples, astronomical practice and regional institutions.

The biography emphasizes computational procedures rather than reducing Madhava to a precursor of European calculus.

The exact date records publication of the study, while Madhava's life remains dated only approximately.

The 1 September 2024 article follows numerals, zero and mathematical astronomy from India through Baghdad into Europe.

His approximation of pi, sine methods and computational astronomy are placed beside better-known Greek achievements.

It argues that British education still underrepresents the Indian foundations of numerical methods used across the modern world.

The paper translates Sanskrit verses and compares four procedures used to compute inverse-sine values.

Kerala astronomers combined approximation, lookup methods and repeated calculation for different ranges of input.

Jyeshthadeva's procedure for circumference is examined alongside arcsine computation.
