Answer 1

The concept of zero as a number was developed by Indian mathematicians around the 5th century CE, with the most notable figure being Brahmagupta. He used a symbol for zero and established rules for arithmetic involving it, recognizing its importance as a placeholder and a concept in calculations. The invention of zero was crucial for advancements in mathematics, allowing for the development of a place-value system and facilitating more complex calculations. Zero eventually spread to the Islamic world and then to Europe, revolutionizing mathematics globally.
