Roman Numerals is a type of numeral notation that was once employed by the Romans. The Roman numeral is an additive and subtractive number system in which letters are employed to represent specific base numbers and arbitrary integers. A roman number is XLVII, which is equivalent to 47 in numerical form. Roman numerals are represented by a unique set of symbols that includes the English alphabet. In roman numerals, 5 is represented by V. It may be used to name anything, such as Class I, Class II, Class X, and so on.
In this article, Knowledge Glow will go through roman numerals in depth.
Roman numerals are an old number system that is still widely used today. Alphabets are used to express fixed positive integers in roman numerals. I, II, III, IV, V, VI, VII, VIII, IX, and X indicate 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 correspondingly.
Following 10, the roman numbers are XI for 11, XII for 12, XII for 13,… to XX for 20. The table below lists the most frequent roman numerals now used to denote basic numbers.
I | V | X | L | C | D | M |
1 | 5 | 10 | 50 | 100 | 500 | 1000 |
The roman numerals table below depicts Roman numerals from 1 to 1000, such as 1, 2, 3,…, 10, 11, 20, 30, 50, 100, 500, and 1000. We can simply write roman numbers from 1 to 1000 using the chart.
The list of Roman numerals or Roman numbers from 1 to 100 follows. The guidelines for writing the roman letters from 1 to 100 are described here.

Although roman letters are used in English alphabets, not all alphabets are roman alphabets. J, U, and W are not considered roman alphabets, and there are 23 roman alphabets out of 26 English alphabets. As a result, the Roman alphabet consists of the following letters: 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 letters are sometimes referred to as roman symbols.
The year 2019 is written as MMXIX, for example.
When representing a number in roman numerals, certain requirements must be fulfilled. Please read the following rules.
Rule 1: If one or more symbols are inserted after a higher-valued letter, add that amount.
Rule 2: Subtract the amount if a symbol comes before a letter with a higher value.
Rule 3: In the case of roman numerals, 1000 is substituted by a bar.
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 |
Example 1: Write 69 in roman numerals.
Solution:
69 = 60 + 9
= (50 + 10) + (10 – 1)
= LX + IX
= LXIX
Thus, 69 = LXIX.
Example 2: Convert 1984 into the roman numeral.
Solution:
Break the number 1984 into 1000, 900, 80 and 4, then perform each conversion
As, 1000 + 900 + 80 + 4 = 1984
1000 + 900 + 80 + 4 = 1984,
So, 1984 = MCMLXXXIV
Example 3: Convert 1774 to Roman Numerals.
Solution:
Break 1774 into 1000, 700, 70, 4 and then do each conversion
1000 = M
700 = DCC
70 = LXX
4 = IV
1000+700+70+4 = 1774,
Hence, 1774 = MDCCLXXIV
Example 4: Compute the following roman numeral MXXII – LXX – LII.
Solution:
Given: MXXII – LXX – LII.
We know that MXXII = 1022, LXX = 70 and LII = 52.
Now, substituting these numbers in the Roman numeral letters, we get;
MXXII – LXX – LII = 1022 – 70 – 52.
MXXII – LXX – LII = 900.
Hence, the number 900 in the Roman numeral is CM.
C represents 100 in roman numerals.
The roman numbers 1 to 10 are represented by:
1 – I
2 – II
3 – III
4 – IV
5 – V
6 – VI
7 – VII
8 – VIII
9 – IX
10 – X
In Roman, 200 is written as CC.
Seven distinct alphabets are used to write Roman numerals. The numerals and alphabets are as follows:
I – 1
V – 5
X – 10
L – 50
C – 100
D – 500
M – 1000
We can write all of the Roman numerals using these alphabets.
XC = 90
800 = 500 + 100 + 100 + 100
500 = D and 100 = C
Therefore,
800 = DCCC
