India and Negative Numbers

Indian mathematicians made significant contributions to mathematics, including the discovery of zero and the concept of negative numbers. Brahma Gupta, a prominent Indian mathematician, developed rules for working with positive and negative numbers, referring to them as fortunes and debts. These rules laid the foundation for solving complex equations and influenced mathematical thought worldwide. Despite initial resistance, these concepts were eventually adopted by European mathematicians centuries later.
