Slight irrelevant correction.
Main numeral systems. The most commonly used system of numerals is the Hindu–Arabic numeral system. Two Indian mathematicians are credited with developing it. Aryabhata of Kusumapura developed the place-value notation in the 5th century and a century later Brahmagupta introduced the symbol for zero.
Let’s just say, numbering has been around since humans could associated fingers to things and preform basic math. Once a more uniform universal numbering system was developed around the 5th century, and was adopted globally, things changed.
