India didn’t just give the world the numeral zero. It developed the decimal system , pioneered early forms of algebra , trigonometry , and even calculus —centuries before their formal discovery in Europe. These innovations shaped the future of commerce, science, astronomy, and digital technology. In this article, we’ll explore how Indian mathematics became the foundation of global progress , influencing everything from early trade to artificial intelligence. 1.
