The Romans were the first to use a special type of numerical notation known as Roman Numerals. This is an additive and subtractive scheme in which letters are used to represent real base numbers and random numbers in the number system, each of which is represented by a different combination of letters or symbols. In this system, numbers are expressed by a mixture or a special collection of letters from the Latin alphabet. Here, we will learn XXXVII Roman numerals, how to convert roman numbers to natural numbers, and also examples of a few more roman numbers.
The Modern Method Employs Seven Characters, Each of Which Contains A Fixed Integer Value As Follows:
All of the symbols used in a system of numerical notation based on the ancient Roman system are known as a Roman numeral. In the Hindu-Arabic numeral system, the symbols I, V, X, L, C, D, and M stand for 1, 5, 10, 50, 100, 500, and 1,000, respectively. When a symbol of equal or greater value is put after another of equal or greater value, its value is added. For example, II = 2 and LX = 60. A symbol put before a symbol with a higher value subtracts the symbol's value. For example, IV = 4, XL = 40, and CD = 400. When a bar is put over a number, it multiplies it by 1,000.
XXXVII Roman Numeral
The value of XXXVII Roman can be found using the addition method of roman numerals. First, we must write each character's or letter's numerical value. The value of XXXVII Roman numerals is then calculated by adding these numbers. This can be achieved in a variety of ways, as discussed below:
Value of XXXVII Roman numeral= 10+10+10+5+2=37
Method 1: Write the numerical value of each letter and add them together to get the answer.
Value of XXXVII can be calculated as 10 + 10 + 10 + 5 + 1 + 1 = 37
Method 2: The numerical values of groups of letters are considered for addition in this system, such as:
Value of XXXVII = (XXX) + (VII) = 30 + 7 = 37
XXXVII = (XXX) + (V) + (II) = 30 + 5 + 2 = 37 is another way of writing.
As a result, XXXVII=37.
The methods described above are used to determine the numerical value of all roman numerals to the greatest degree possible.
XXVI Roman Numerals
We know the value of x is 10,v is 5 and i is 1.
So, value of XXVI Roman numerals = 10+10+5+1=26
XXXVI in Numbers
Value of XXXVI =10+10+10+5+1=36
How to Convert Roman Numerals to Numbers?
Before proceeding to the conversion of roman numbers to numbers, it is essential to first gain a thorough understanding of how this system of numbers is represented. Consider the following series of events:
The Roman numbers from 1 to 20 are written as I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XVIII, XIX, and XX.
As a result, the notations IV and IX can be read as “one less than five, i.e. 4” and “one less than ten, i.e. 9,” respectively. Also, VI and XI can be read as “one more than five, i.e. 6” and “one more than ten, i.e. 11” respectively. Large numbers can also be expressed in this way using special notations.
The value of XXVI Roman number = 10+10+5+1=26
XXVII roman number is equivalent to 27, as we know the value of x is 10, v is 5 and I is 1.
The calculations to get the number for a given roman numeral are shown in the table below.

Numbers Nearer to XXXVII
Below are the numbers that are similar to, less than, and greater than XXXVII.
Value of XXX = 10 + 10 + 10 = 30
Value of XXXI = 30 + 1 = 31
Value of XXXII = 30 + 1 + 1 = 32
Value of XXXIII = 30 + 1 + 1 + 1 = 33
Value of XXXIV = 30 + 4 = 34
Value of XXXV = 30 + 5 = 35
Value of XXXVI = 30 + 6 = 36
Value of XXXVII = 30 + 7 = 37
Value of XXXVIII = 30 + 8 = 38
Value of XXXIX = 30 + 9 = 39
Value of XL = 40
Value of XLI = 40 + 1 = 41
Value of XLII = 40 + 1 + 1 = 42
Value of XLIII = 40 + 1 + 1 + 1 = 43
Students will be able to find the list of roman numbers from 100 to 1000 after practising the below list.

Rules for Converting Numbers to Roman Numerals
The following are the three most important laws for writing and reading Roman numerals.
A letter can only be repeated three times, such as XXX = 30, CC = 200, and so on.
If one or more letters are put after a letter with a higher value, multiply by that number.
VII can be written as 7 (5 + 2 = 7)
Value of LXXX is 80 and can be written as (50 + 10 + 10 + 10 = 80)
Value of MCCC is 1300 and can be written as (1000+100 + 100 + 100 = 1300)
Remove the sum if a letter is put before a letter with a higher value.
CM can be written as 900 (1000 – 100 = 900)
IX can be written as 9 ( 10 – 1 = 9 )
XC can be written as 90 (100 – 10 = 90)
How to Write Roman Numerals?
Students must know the rules for writing Roman numerals. There are some important rules that students must remember for writing Roman Numerals which are given here:
Students must remember that the letters I, C, and X can be repeated three times in succession whereas the letters L, V, and D cannot be repeated in succession. The number is not a valid number if these three letters are used in succession.
When we write a lower value digit to the left of a higher value digit, it is subtracted.
When we write a lower value digit to the right of a higher value digit, it is added.
Only the three letters that are I, C, and X can be used as subtractive numerals.
Uses of Roman Numerals

Facts about Roman Numerals
Some facts about Roman Numerals are given here:
Roman numbers are written starting from the biggest unit on the left and going towards the right.
A numeral can be used three times to add and form a number but it cannot be added more than three times. For example, XXX= 30
If you want to make 40, you must subtract from the larger unit, for example, 40 can be written as XL. Does this mean 50-10 = 40
