Jonathan J Crabtree reveals how India's mathematics education crisis stems from fatally flawed Western arithmetic foundations and demonstrates how returning to Brahmagupta's ancient principles could revolutionize global math learning. Discover why Indian students ranked 73rd out of 74 countries in PISA testing, how a 1570 mistranslation corrupted mathematics education for 450 years, and learn why Crabtree spent 40+ years rebuilding elementary mathematics from zero. This educator and researcher sold his house and quit his executive career while exposing the pedagogical failures destroying mathematical intuition in millions of children. Essential viewing for educators, parents, and policymakers seeking evidence-based solutions to math anxiety and India's STEM education challenges. Key Points: Understand why India's ancient mathematical supremacy declined from 33% global GDP to bottom PISA rankings Discover Brahmagupta's 7th-century laws that make negative numbers intuitive for primary students Learn how British colonial pedagogy created "fatally flawed" arithmetic foundations still taught today Explore the "Podematic" visual learning system using brain science, cartoons, and songs See proof that teaching methodology—not student ability—causes math failure globally Access free digital mathematics resources designed to restore India's mathematical heritage A Sangam Talks presentation on reclaiming indigenous knowledge systems and transforming education through authentic Indian mathematical traditions.

Crabtree is a guest lecturer at Indian universities. Having reviewed writings in Latin, Greek, Arabic and Sanskrit, his provocative presentations reveal how India’s ‘lost’ ancient mathematics is vastly superior to the western maths taught today.
