Explanation

The invention of zero as both a number and a placeholder revolutionized mathematics by allowing people to write extremely large numbers easily and perform complex calculations using a positional base-10 system. Without zero, distinguishing numbers like 12, 102, and 120 in writing would be highly complicated.
