XXV Roman Numerals
In this article, we will discuss roman numerals and we will also learn how we can convert roman numerals into numbers. First, let us know more about roman numerals. Roman numerals as the name suggest deriving their name from Rome in ancient times. It was widely used not only in Rome but also in other parts of Europe as well.

XXV Roman Numerals Conversion into Numbers
Roman Numerals are not depicted by numbers as is the case normally with the help of alphabets such as X, XI… and so on. Some alphabets signify a large number such as ‘M’ signifies ‘thousand’. In this article we will learn about how we can convert them into numbers, by following the steps given below:
Step 1: First we need to understand that roman numerals are a combination of one or more than one alphabet so we need to add the value of one alphabet with another so as to get the value depicted by the alphabet/alphabets.
Step 2: Each alphabet has one value that carries value, for example ‘I’ means 1 (one), IV means 4 ( four ) and X stands for 10 (Ten).
Step 3: Identify the alphabets and their value and the order in which they Are placed, eg XXV, X denotes ten (10), followed by X again which again implies ten (10) and then V in the end ‘V’ means five (5) so we will add all the numbers which in this case is 10 + 10 +5 = 25. It is also called the Addition Method whereby all the alphabets are added to get the desired number. Where a greater alphabet follows a smaller one they are added with each other to the desired result.
Step 4: Another method that is also used in some cases is subtracting the alphabets placed before with the one following it for eg IV, which denotes 4 (four), it has two letters I and V denoting I as one and V as five so the one following the next letter is subtracted to get the answer i.e V is subtracted from I to get IV or 5 – 1 = 4. This is also called the subtraction method. it should be kept in mind that if a smaller letter follows a greater alphabet the same is subtracted to get the desired result.
Another important thing to note is that the same number cannot be added or written more than three (3) times at once for eg XXX is 10+10+10= 30 But XXXX does not mean 40, it is not valid
Some other important letters and their number is noted below :
L means 50
M means 1000000
D means 500000

Step 1: First we will convert roman numerals into numbers by following the above steps. For example XXV means 10 + 10+ 5 = 25 .
Step 2: Convert the numbers into words and then add them, for eg XXV means ten + ten + five = twenty-five
