History Of Mathematics Mock Tests

The following passage is an excerpt from an article about the history of mathematics. The development of zero as a number and not merely a placeholder was one of the most profound intellectual achievements in the history of mathematics. While the concept of "nothing" is abstract, its mathematical formalization required a conceptual leap that not all ancient civilizations made. The Babylonians used a placeholder symbol for zero in their base-60 number system as early as the third century BCE, but they did not treat zero as a number in its own right—it could not be used in calculations. The ancient Greeks, particularly the philosophers Aristotle and Zeno, grappled with the concept of the void or empty space, but most rejected the idea that "nothing" could exist as a physical or mathematical reality. The breakthrough came in India, where mathematicians in the fifth century CE began treating zero as a number with its own properties. The Indian mathematician Brahmagupta, writing in 628 CE, provided the first known rules for arithmetic operations involving zero, including addition, subtraction, and multiplication. (He incorrectly stated that zero divided by zero equals zero, a problem that would not be resolved until much later.) The Indian concept of zero—called "shunya," meaning "empty" or "void"—spread to the Islamic world through trade and scholarly exchange, where it was adopted by mathematicians such as Al-Khwarizmi. From the Islamic world, the concept traveled to Europe, where it was initially met with suspicion. The Italian mathematician Leonardo of Pisa (known as Fibonacci) introduced the Indian number system, including zero, to Europe in his 1202 book Liber Abaci. However, European scholars were slow to accept zero, partly because it conflicted with long-held philosophical and religious beliefs about the nature of nothingness. It was not until the development of algebra in Renaissance Europe that zero became fully integrated into mathematical practice, enabling the creation of the number line, negative numbers, and ultimately calculus. According to the passage, what was the key difference between the Babylonian and Indian treatments of zero?
