## Zero in Roman Numerals

Roman numerals were created as a system for bartering and trading. They utilized the Latin word “nulla,” which meant zero, instead of a Roman numeral. Roman numerals begin counting at one and lack a sign for “0.” This occurs because the Romans’ additive system did not require a zero. Meaning, in the roman system, figures are added together and are always equal.

• However, in our current system, the value of the number varies on its location.
• Because of this, roman numerals do not have a zero.
• Furthermore, the Roman system uses the term ‘nulla’, which means none.
• The word comes from Latin and is used in the place of zero in the Roman numerical system.

Summary:

## Why Roman Numerals don’t have Number Zero?

The reason why Roman numerals don’t have the number zero is that the Roman system was mainly used to estimate the value of goods while trading. Since the value cannot be zero, it was never required. However, instead of zero, the Latin term ‘nulla’ is used in the Roman system which means none.
