Roman Numerals 1 to 1000 | Roman Numbers Chart, Rules

Roman Numeral – 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.

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.

The Roman Numbers for 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 are discussed in the table below,

Roman Numerals Conversion

900	CM	1000 – 100
1000	M	1000

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.

Roman Numbers to Numbers

• Write down the numerical value of each Roman numeral symbol
• I: 1
• V: 5
• X: 10
• L: 50
• C: 100
• D: 500
• M: 1000
• Start from the leftmost numeral.
• If a numeral is smaller than the one immediately after it, subtract its value from the next numeral.
• If a numeral is equal to or greater than the one immediately after it, add its value.

Example

Convert the Roman numeral “IV” to a number.

• I: 1
• V: 5
• Since I come before V, we subtract its value from V. So, IV = 5 – 1 = 4.
• Therefore, IV in Roman numerals is equivalent to 4 in numbers.

Convert the Roman numeral “XII” to a number.

• X: 10
• I: 1
• I: 1
• Since I come before II, we add their values together: II = 1 + 1 = 2.
• Adding X (10) to II (2), we get 10 + 2 = 12.
• Therefore, XII in Roman numerals is equivalent to 12 in numbers.

Convert the Roman numeral “XLV” to a number.

• X: 10
• L: 50
• V: 5
• Since X comes before L, we subtract its value from L: XL = 50 – 10 = 40.
• Adding V (5) to XL (40), we get 40 + 5 = 45.
• Therefore, XLV in Roman numerals is equivalent to 45 in numbers.

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. 

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. 

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  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 +  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

Subtractive Rule of Roman Numerals

The subtractive rule of Roman Numerals is made clear in the table discussed below,

Write	Instead of	For the Value of
IV	IIII	4
IX	VIIII	9
XL	XXXX	40
XC	LXXXX	90
CD	CCCC	400
CM	DCCCC	900

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, 

2023 = MMXXIII

Example 3: Simplify MXVII – LXV + II

Solution:

Given: 

MXVII – LXV – II

We know that 

• MXVII = 1017
• LXV = 65
• II = 2

Now, substituting these we get;

MXVII – LXV – II = 1017 – 65 + 2 = 954

Example 4: Simplify C + XLVII – XVII

Solution:

Given: 

C + XLVII – XVII

We know that 

• C = 100
• XLVII = 47
• XVII = 17

Now, substituting these we get;

C + XLVII – XVII = 100 + 47 – 17 = 130
