How do you write zero in Roman numerals?

Answer 1

There is no zero in roman numerals. It originated in India and was later incorporated in the current number system.

Roman numerals were basically designed for counting purpose, so mathematical operations could not be performed on them. This was the greatest handicap with their number system.

The Indian number system was designed to carry out mathematical operations and calculations and hence zero was evolved in India.

Answer 2

there is no 0

Zero
In general, the number zero did not have its own Roman numeral, but the concept of zero as a number was well known by all medieval computists (responsible for calculating the date of Easter). They included zero (via the Latin word nulla meaning nothing) as one of nineteen epacts, or the age of the moon on March 22. The first three epacts were nullae, xi, and xxii (written in minuscule or lower case). The first known computist to use zero was Dionysius Exiguus in 525, but the concept of zero was no doubt well known earlier. Only one instance of a Roman numeral for zero is known. About 725, Bede or one of his colleagues used the letter N, the initial of nullae, in a table of epacts, all written in Roman numerals.

A notation for the value zero is quite distinct from the role of the digit zero in a positional notation system. The lack of a zero digit prevented Roman numerals from developing into a positional notation, and led to their gradual replacement by Hindu-Arabic numerals in the early second millennium. On the other hand, the lack of positional notation may have prevented the Romans to develop a "zero". Which affected which is not certain.

Answer 3

You don't. Negetive numbers - not either.

"Another zero was used in tables alongside Roman numerals by 525 (first known use by Dionysius Exiguus), but as a word, nulla meaning nothing, not as a symbol. When division produced zero as a remainder, nihil, also meaning nothing, was used. These medieval zeros were used by all future medieval computists (calculators of Easter). An isolated use of their initial, N, was used in a table of Roman numerals by Bede or a colleague about 725, a zero symbol."

Answer 4

No zero in Roman numerals. It is just assumed there is nothing until a numeral is added. m

Answer 5

You don't. The Romans never got around to inventing the zero. I suppose that you could invent something that would look right, but not many people will get it.
