Many years ago why did people find they needed negative numbers?

People found a need for negative numbers to effectively represent debts, losses, and situations where quantities could fall below zero, such as in accounting and trade. For instance, if someone owed money, the negative value could indicate their debt. Additionally, negative numbers were essential in mathematics for solving equations and understanding concepts like temperature below freezing, thereby expanding the number system to encompass a broader range of real-world scenariOS.
