XXXVII Roman Numeral - Conversion, Rules, Uses, and FAQs

Dhristi JEE 2022-24

What are Roman Numerals?

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

 

Alternatively,

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.

Rules for Converting Numbers to Roman Numerals

The following are the three most important laws for writing and reading Roman numerals.

  1. A letter can only be repeated three times, such as XXX = 30, CC = 200, and so on.

  2. 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)

 

  1. 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)
