Mathematics in Ancient India: Zero to Infinity

Every time you type a phone number, check a price tag, or calculate a tip, you are using Indian mathematics. The decimal place-value system — the way we write numbers today — was invented in India. The concept of zero as a number? India. The infinity symbol? India. This is not nationalist chest-thumping. It is historical fact recognized by mathematicians worldwide. India's contributions to math are so foundational that modern civilization literally could not function without them.
