# Roman Numerals to Number

In our modern world, we use numbers to represent quantities. But before the introduction of Arabic numerals in Europe during the Middle Ages, Roman numerals were used to represent numbers. While they may look complicated at first glance, Roman numerals are actually quite simple once you understand the basic rules. In this blog post, we will take a closer look at Roman numerals and how to convert them to regular Arabic numbers. So let's get started!

Roman numerals are a numeral system used to represent numbers in ancient Rome. In this system, letters are used to represent numbers. The basic rules for converting Roman numerals to numbers are as follows:

I = 1

V = 5

X = 10

L = 50

C = 100

D = 500

M = 1000

There are a few rules which must be followed when writing Roman numerals. First, the letter I can only be used once per numeral. Second, V and X can only be used once per numeral. Third, L, C, D, and M can only be used once per numeral. Fourth, the order of the letters is important. Fifth, when a letter is repeated, its value is added to the total. Sixth, when a letter is followed by a letter of greater value, the first letter is subtracted from the second.

Now that we know the basic rules for converting Roman numerals to numbers, let's try some examples.

Example 1:

I + I + I = 3

Example 2:

V + I = 6

Example 3:

X + I + X = 21

As you can see, converting Roman numerals to numbers is not difficult once you know the rules. Just remember to follow the rules and you will be able to convert any Roman numeral to a number.
