The number "4" is the Roman numeral of the number 4. In the Roman number notation system, "I" is the equivalent of the number 1 in the Hindu-Standard arabic numbering system, and "V" is the equivalent of the number five. This numbering arrangement is still used in sure applications in the earth.

What are Roman Numerals?

Roman numerals are part of the numbering arrangement used by ancient Romans. Instead of the numbers ordinarily used today, they relied on letters to stand for numbers. This was the standard number notation used throughout Europe during the Middle Ages, and they used it for nearly 2 millennia before converting to the Hindu-Standard arabic number notation.

This numerical notation uses the symbols I, 5, 10, 50, C, D, and M in place of the Hindu-Arabic numbers 1, 5, x, l, 100, 500 and 1000. These symbols represent larger numbers when a bar is placed over them. For example, a bar over the alphabetic character X denotes the number 10,000. There is no symbol for zilch in this system, as this was a contribution from Arabic mathematicians.

In the standard form of Roman numerals, each number has a stock-still value. The letter of the alphabet combinations must be added and subtracted post-obit the traditional rules. In one alternative course of Roman numerals, users add symbols together. For instance, the number 9 in standard Roman numeral format is IX.

In add-on to the standard form of Roman numerals, in that location were alternative forms that did not follow all of the standard rules. For example, it's not uncommon to find the number nine written every bit XIIII instead of 9. Another alternative course leaves out the letters V and L. In that instance, the number five is written as IIIII.

However, information technology is yet common to see Roman numerals in other domains like royal titles, on watches and clocks, buildings, and in entertainment. Publishers sometimes separate chapters in books with Roman numerals, and musicians employ them to indicate major and minor triads.

Adding and Subtracting Roman Numerals

It's important to notation the position of the letters when adding and subtracting Roman numerals. When a letter appears subsequently a larger or equal symbol, you add the numbers. For example, in the combination Vi, the value of I is smaller than the value of V. You and so add together one to 5, which equals six. The contrary is true for subtraction. 9 is 9. Since the value of I is smaller than the value of X, you subtract 1 from ten, which equals ix.
