>>22994873 (OP)Here's the tip of the iceberg of Indian contributions:
>Be the very progenitors of civilization itself>The Hindu numerals (0–9) with place-value notation>a concept so fundamental that it's literally the first Mathematical concept taught to kindergarteners>forms the foundation of modern arithmetic: used in every calculator, grocery bill, credit card payment, large numbers, binary computing, and digital technology (can't do any of this shit with Roman numerals)>x + (−x) = 0 made standard>paves the way for algebra and daily applications like finance and engineering>solutions for linear and quadratic equations>establishes the basis of modern numeric routines>Aryabhata advances trigonometry and algebra>introduces sine tables and systematic approaches to solving equations>Kuttaka method provides solutions for Diophantine equations>lays groundwork for modular arithmetic>underpins cryptography, secure transactions, and PIN systems>Bhaskara II’s “Lilavati” covers arithmetic, algebra, geometry, and combinatorics>foundation for interest calculations, construction, and everyday tasks>Chakravala method solves Pell’s equation, is an early step in public-key cryptography>Madhava and Kerala School work out infinite series for π, sine, and cosine>Pioneer calculus (series representation) centuries before Newton>critical for modern analytics, weather models, and rocket guidanceThis doesn't cover everything, so here's a wikipedia page for an exhaustive list

And these are just India's MATHEMATICS contributions.
