Why Roman numerals don't have the number zero?
The Roman numerals are a unique system of numerical notations used by the Romans represented by a set of certain letters.
Answer: Roman numerals start to count from one and didn't need to have a zero in their additive system as it was basically designed to estimate the prices of goods and trading business.
Let us explore more about '0' and its relation with Roman numerals.
Roman Numeral system is based on the pattern and not on a technique. They have specific signs to represent different numbers.
I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000
For subsequent numbers, the sign is repeated and not added.
- 1 = I and 2 = II
- 10 = X and 20 = XX
But the word NULLA (the Latin word meaning "none") used to represent the number zero as 0 does not have its own Roman numeral.
