### Roman Numerals 1 to 100 | Definition, Chart, Conversion List

**Roman numerals** are an ancient number system, originally introduced by the Romans. This ancient number system uses the English alphabet to represent different numbers. All the numbers are pre-defined with a specific alphabet. For example, I is used to denote 1, V is used to denote 5, X is used to denote 10, L is used to denote 50, and so on. Hence, I, V, X, L, etc. are also known as Roman symbols or Roman alphabets.

Nowadays, roman numerals have a wide range of applications, which you encounter in your daily life. Roman numbers are used in schools to represent the classes, such as Class I, Class II, Class V, etc. Apart from this, roman numerals are also used in titles and on clock faces to represent the time. All the roman symbols are English alphabets, but all the English alphabets are not roman symbols.

Let us understand what Roman numbers are, how to write them, and the conversion of Roman numerals. Scroll down to find out more.

**Roman letters**

Roman letters are the letters of the English alphabet which are used to write Roman numbers or Roman numerals. As discussed above, all the roman numerals are English alphabets, but not all English alphabets are roman numerals. A total of 23 alphabets are used to represent roman numerals.

The letters J, U, and W are not considered the Roman alphabet since they are not used in it.

The list of roman alphabets is given below:

Roman Alphabets: A, B, C, D, E, F, G, H, I, K, L, M, N, O, P, Q, R, S, T, V, X, Y, and Z. |

These roman alphabets are otherwise called roman symbols.

**What are the 8 rules of Roman numerals?**

There are certain rules to be followed for representing and learning Roman numerals to avoid possible mistakes. So, the eight basic rules for roman numerals are:

**Rule 1:**When the same numerals are repeated after each other, the actual number represented by the numerals is the sum of the values each numeral represents.- For example, III = 1 + 1 + 1 = 3
- Here, the numeral I is repeated three times, so the number represented by III is the sum of I three times. Since I is equivalent to 1, we added 1 three times and the final answer came out to be 3.

**Rule 2:**No roman numeral can be repeated more than three times in a row.- For example, in numeral form, 3 can be written as III but 4 can not be written as IIII.

**Rule 3:**The Roman symbols, V, L, and D, may never be repeated to represent any number.**Rule 4:**When a roman numeral is placed after another roman numeral that holds a greater value, the final result will be the sum of the numerals.- For example, if, VI = 5 + 1 = 6
- Here, the numeral V is equivalent to 5, and the numeral I is equivalent to 1, and since I is placed after V, which holds a greater value, then the actual number represented by VI is the sum of V and I, that is, 5 + 1 = 6.

**Rule 5:**When a roman numeral is placed before another roman numeral that holds a greater value, the final result will be the difference between the numerals.- For example, XL= 50 – 10 = 40
- Here, the numeral L is equivalent to 50 and the numeral X is equivalent to 10, and since X is placed before L, which holds a greater value, then the actual number represented by XL is the difference between L and X, that is, 50 – 10 = 40.

**Rule 6:**When a roman numeral that holds a smaller value is placed between two numerals that hold greater values, the numeral having the smaller value is subtracted from the numeral on its right.- For example, XIX = 10 + (10 – 1) = 10 + 9 = 19
- Here, the numeral X is equivalent to 10 and the numeral I is equivalent to 1, and since I is placed between X’s which hold a greater value than I, then the actual number represented by XIX is the difference between the second X and I and then their sum with the first X, that is, 10 + (10 – 1) = 10 + 9 = 19.

**Rule 7:**In roman numerals, the number 1000 is replaced by a bar.- For example, 5000 can be written as V with a bar over it.

**Rule 8:**In roman numerals, there is no representation for the number zero (0).

**Tips to remember Roman numerals**

Since we are more comfortable with working on normal numbers, it might take a little more time and effort to learn roman numerals in that way. So here are a few tips that might help:

**Practicing and Solving Problems:**The more questions you solve based on roman numerals, the more you will learn and get familiar with the concept in a better way. This tip works magically if you really focus on solving the problems.**Using Mnemonics:**It is one of the most effective and fun ways of learning a new concept. You can use it to learn Roman numerals. You can make your own mnemonic as per your liking. One such mnemonic is**M**y**D**og and**C**at**L**ike**X**tra**V**itamins. Here, the bold letters represent roman numerals in descending order, as M is equivalent to 1000, D is equivalent to 500, C is equivalent to 100, L is equivalent to 50, X is equivalent to 10, and V is equivalent to 5.

**Roman numerals conversions**

Now let us understand how to convert roman numerals to numbers and numbers to roman numerals using the solved examples provided below:

**Conversion of numbers to Roman numerals**

When writing roman numerals, we first expand the provided number as necessary using addition or subtraction in accordance with the rules, and then we write the roman symbols based on the value each sign denotes.

**Convert 2033 to Roman NumeralsSolution: **2033 can be written as MMXXXIII in the roman numeral form.

Here, we expanded 2033 as 1000 + 1000 + 10 + 10 + 10 + 1 + 1 + 1.

So, for representing 1000, we use M, for representing 10, we use X, and for representing 1, we use I.

When we substitute the Roman symbols in place of the value they hold, we get the desired answer.

**Conversion of Roman numerals to numbers**

To convert roman numerals to normal numbers, we split the entire roman numeral into single numerals and then write their respective numeric values and finally add or subtract them, as per the rules, to get the final answer.

**Convert XIV to Numeric ValueSolution:** the numeric value of XIV is 14.

Here, X is equivalent to 10, I is equivalent to 1, and V is equivalent to 5.

As per rule, since I is placed between X and V, which has greater numeric values than I, the numeric value of I will be subtracted from the numeric value of V because V is on the right of I. Then the result will be added to the numeric value of X to get the final answer.

X = 10, I = 1 and V = 5

X + V – I = 10 + 5 -1

XIV = 10 + (5 – 1) = 10 + 4 = 14

XIV = 14

**Solved Examples **

A few solved examples based on Roman Numerals are given below:

**Question 1: Write the numeric form of MCII.Solution: **Here, M is equivalent to 1000, C is equivalent to 100, and I is equivalent to 1.

First, we will split MCII into single numerals and then perform addition or subtraction on their respective numeric values.

MCII = M + C + I + I

= 1000 + 100 + 1 + 1

= 1102

**Question 2: Write 53 in roman numeral form.Solution:** To convert 53 into a roman numeral, we need to expand 53 and then write the roman symbols according to the value a particular symbol holds.

So, 53 = 50 + 3

= 50 + 1 + 1 + 1

Since, 50 is equivalent to L and 1 is equivalent to I. Hence, 53 can be written as LIII in roman numeral form.

**Question 3: Convert 1976 into the roman numeral form.Solution: **To convert 1976 into a roman numeral, we expand 1976 and then write the roman symbols according to the value a particular symbol holds.

So, 1976 = 1000 + 900 + 70 + 6

= 1000 + (1000 – 100) + (50 + 10 + 10) + (5 + 1)

Since, 1000 is equivalent to M, 100 is equivalent to C, 10 is equivalent to X, and 1 is equivalent to I.

1976 = 1000 + (1000 – 100) + (50 + 10 + 10) + (5 + 1)

= M + (M – C) + (L + X + X) + (V + I)

= M + CM + LXX + VI

= MCMLXXVI

Hence, 1976 can be written as MCMLXXVI in roman numeral form.

**Question 4: Write the numeric form of DXII.Solution: **Here, D is equivalent to 500, X is equivalent to 10, and I is equivalent to 1.

First, we will split DXII into single numerals and then perform addition or subtraction on their respective numeric values.

DXII = D + X + I + I

= 500 + 10 + 1 + 1

= 500 + 10 + 2

= 512

**Question 5: Compute the roman numeral: MCXX – VIISolution:** Here, M is equivalent to 1000, C is equivalent to 100, X is equivalent to 10, V is equivalent to 5, and I is equivalent to 1.

First, we will split MCXX and VII into single numerals and then perform addition or subtraction on their respective numeric values separately.

MCXX = M + C + X + X

= 1000 + 100 + 10 + 10

= 1000 + 100 + 20

= 1120

VII = V + I + I

= 5 + 1 + 1

= 7

Now, on subtracting MCXX and VII, that is, 1120 and 7, we get:

MCXX – VII = 1120 – 7

= 1113

To convert 1113 into roman numeral, we expand 1113 and then write the roman symbols according to the value a particular symbol holds.

So, 1113 = 1000 + 100 + 10 + 3

Since, 1000 is equivalent to M, 100 is equivalent to C, 10 is equivalent to X, and 1 is equivalent to I.

1113 = 1000 + 100 + 10 + 3

= M + C+ X + (I + I + I)

= M + C + X + III

= MCXIII

Hence,

MCXX – VII = 1113

= MCXIII
