Roman Numerals are the symbols from the Latin letters used by Romans for daily transactions and counting purposes. In this topic, we will learn how to write Roman Numerals and their uses.

Roman Numerals 1 to 100

Roman Numerals use symbols to represent number systems. Ancient Romans used the letters I, V, X, L, C, D, and M to represent the number system. The unavailability of zero at that time and the lack of other mathematical operations made the Roman Numerals obsolete in recent times. For example, we write 15 as XV.

How to Write Roman Numerals 1 to 100

Roman Numerals rely on specific symbols, and it has rules of addition and subtraction. The basic symbols in Roman Numerals are:

  • I = 1
  • V = 5
  • X = 10
  • L = 50
  • C = 100
  • D = 500
  • M = 1000

Using the above symbols, we can combine the Roman Numerals for the numbers easily. There are two basic methods of writing Roman Numerals, they are

  1. By Expansion Method
  2. By Grouping Method
     

By Expansion Method

Through the expansion method, we break down the numbers into tens and one's parts and then convert them into numerals.


Step 1: Break the numbers into ones and tens of parts.


Step 2: Write Roman Numerals for each part.


Step 3: Combine all the parts to get the numerals.

Example: For the number 99.


Step 1: Break the numbers 


90 + 9 = 99


Step 2: Add Roman Numerals for each part


The Roman Numeral of 90 is XC.


The Roman Numeral of 9 is IX.


Step 3: Combine all the parts

90 (XC) + 9 (IX) = XCIX.

Therefore, the Roman Numeral of 99 is XCIX.

By Grouping Method

Grouping method directly from the number by combining Roman Numeral symbols directly. It uses addition and subtraction rules.

Step 1: Start writing numerals for the largest number.


Step 2: Smaller numbers are either getting added or subtracted. Following the rule of adding and subtraction is mandatory. 


Addition: smaller numeral after the larger numeral.


Subtraction: smaller numeral before the large numeral.

Example: For the number 12.


Step 1: Start with the larger numbers. 


While splitting, we will get 10 and 2 


The Roman Numeral of 10 is X


Step 2: Add or subtract the smaller number

If we add 2 to 10 it will become 12.


The Roman Numeral of 2 is II


Therefore, the Roman Numeral of 12 is XII.

Rules for Writing Roman Numerals 1 to 100

Roman Numerals follow rules to make sure the number is written correctly. Here are some main rules given below

  • Rule 1: Addition Method
  • Rule 2: Repetition Method
  • Rule 3: Subtraction Method
  • Rule 4: Limitation Rule

Rule 1: Addition Method

In Roman Numerals, if the smaller numeral comes after the large numeral, then we need to add their values.


Example: If the given number is XII. We can see that the number X refers to 10 and the other number refers to 2. So in this, the smaller numeral is after the large numeral, so we need to add the 10 and 2 to get the value 12.

Rule 2: Repetition Method

The Roman Numeral can be repeated up to three times to increase its value. The numbers cannot be repeated after three times. Only symbols like I, X, C, and M can be repeated and V, L, and D cannot be repeated.


Example: XXX = 10 + 10 + 10 = 30 repeating the numeral X for the fourth time is not allowed.

Rule 3: Subtraction Method

If the smaller numeral comes before the large numeral, then we need to subtract the smaller numeral from the larger numeral to get the number. There are three rules in subtraction, they are,

  • I can be subtracted from V and X.
  • X can be subtracted from L and C.
  • C can be subtracted from D and M.

Example: In the number IV. Here, V is the biggest numeral and I is the smallest numeral. As we see that the smaller numeral is before the larger numeral, we need to subtract to get the number. V (5) - I (1) = IV (4).

Rule 4: Limitation Rule

Roman Numerals consist of several limitations, they are:

  • A numeral cannot be repeated more than three times. For example, III (3) cannot be repeated more than 3 times, instead we use IV for writing 4.
  • Subtraction cannot be done with the non-pair numbers. For example, XI here X (10) - I(1) gives IX is applicable but IC, C (100) - I(1) is not applicable.
  • Only one subtraction can be allowed in one numeral. For example, XL (40), L (50) - X (10) is applicable to get 40 but XXL is not applicable to get the number 30.

Problem 1

Write the Roman Numerals for 28 using the breakdown method.

Okay, lets begin

The Roman Numeral of 28 is XXVIII.

Explanation

Step 1: Break the numbers into tens and ones.


 28 = 20 + 8 


 Step 2: Add numerals to each part.


 The Roman Numeral of 20 is XX.


 The Roman Numeral of 8 is VIII.


Step 3: Combine the parts


20 (XX) + 8 (VIII) = XXVIII (28).
 

Well explained 👍

Problem 2

Add XX + VI.

Okay, lets begin

XXVI

Explanation

Adding XX (20) and VI (6) = XXVI (26).

Well explained 👍

Problem 3

Subtract L - XXV.

Okay, lets begin

XXV

Explanation

L = 50
XXV = 25
50 - 25 = 25
= XXV.

Well explained 👍

Problem 4

Write the Roman Numeral of 100.

Okay, lets begin

C
 

Explanation

The Roman Numeral of 100 is C.

Well explained 👍

Problem 5

Add 200 + 25 and write the answer in Roman Numeral.

Okay, lets begin

CCXXV.

Explanation

200 + 25 = 225


CC + XXV = CCXXV.
