# Roman Numerals 1 to 100 | Roman Numbers Chart, Rules

Roman numerals are a numerical notation system that originated in ancient Rome. The Roman number system uses seven symbols, each with a fixed integer value, to represent numbers. The symbols are I, V, X, L, C, D, and M, which represent 1, 5, 10, 50, 100, 500, and 1,000, respectively. Different arrangements of these symbols represent different numbers. For example, the Roman number LX is equal to 60, which is (50 + 10). These roman numerals are I, II, III, IV, V, VI, VII, VIII, IX, and X represent 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 respectively.

In Roman numerals, if a symbol with a greater value is placed after another symbol of greater or equal value, the values are added. However, if a symbol of a smaller value is placed before a greater value symbol, the smaller value is subtracted. Roman numbers were the standard way of writing numbers in Europe until the Late Middle Ages. They are still used in many places today.

Let’s learn about Roman numerals, their chart, and conversion rules in detail in subsequent sub-sections.

## What are Roman Numerals

Roman numerals are a number system that uses combinations of letters from the Latin alphabet (I, V, X, L, C, D, M) to represent numbers. Each letter has a fixed numerical value, and they are arranged in specific ways to represent different numbers.

Roman numerals are a system of numerical notation that originated in ancient Rome. They were used extensively throughout the Roman Empire and beyond.

Note– Roman Number System does not have any symbol for zero (0) unlike other number systems.

So the question arises: to increase the number by a multiple of 10 what symbol we must use initially different symbols are used for 10, 100, 1000, and other. But this seems very complex to use different symbols, hence Roman Number System is not further used today.

## Roman Letters

English Letters are also called Roman Letters but all English letters are not Roman letters. In English, we have 26 letters namely,

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, and Z.

While, in Roman Letters, we have 23 letters namely,

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

Observing the above-given letters we can say that Roman Numerals have 23 letters of English Letters except, J, U, and W.

## Rules to Write Roman Numerals

While writing Roman Numerals, we have to follow these conversion rules :

Rule 1. If a bigger letter proceeds to a smaller then the letters are added.Â

For example XI, X > I, so XI = X + I = 10 + 1 = 11

Rule 2. If a smaller letter proceeds to a smaller then the letters are subtracted.Â

For example IX, I < X, so IX = IX = 10 – 1 = 9

Rule 3. If a letter repeats multiple time they are added

For example XXX = X + X + X = 10 + 10 + 10 = 30

Rule 4. A letter can not be repeated more than three times and Â V, L, and D cannot be repeated, they appear only once.

### Steps of Conversion to Roman Numerals

Let us find the Roman Numerals for 1234.

Here are the steps of conversion into roman numerals:

Step 1: Break the given number in such a form that the value of each part is known in Roman Numerals such as

1234 = 1000 + 100 + 100 + Â 10 + 10 + 10 + 5 – 1

Step 2: Substitute each Roman numeral for the given Hindu numerals,

• 1000 = D
• 100 = C
• 10 = X
• 5 = V
• 1 = I

Step 3: Substitute each value to find the given Roman Numerals.

1234 = DCCXXXIV

## Roman Numerals 1-100 Examples

Here are some solved examples on Roman Numbers.

Example 1: Convert 47 into Roman Numeral.

Solution:

47 = 50 – 3

We know that,

• 50 = L
• 3 = III

Now, 47 = IIIL

Example 2: Convert 2023 into the Roman Numeral.

Solution:

2023 can be broken as,

2023 = 1000 + 1000 + 10 + 10 + 1 + 1 + 1

We know that,

• 1000 = M
• 10 = X
• 1 = I

Thus,Â

2023 = MMXXIII

Example 3: Simplify MXVII â€“ LXV + II

Solution:

Given:Â

MXVII â€“ LXV â€“ II

We know thatÂ

• MXVII = 1017
• LXV = 65
• II = 2

Now, substituting these we get;

MXVII â€“ LXV â€“ II = 1017 – 65 + 2 = 954

Example 4: Simplify C + XLVII â€“ XVII

Solution:

Given:Â

C + XLVII â€“ XVII

We know thatÂ

• C = 100
• XLVII = 47
• XVII = 17

Now, substituting these we get;

C + XLVII â€“ XVII = 100 + 47 – 17 = 130
