Rules for formation of Numbers

We have three different rules to form the roman numerals as numbers. They are multiplication rule, addition rule, and subtraction rule.

Multiplication Rule:

When a roman symbol is repeated in sequence, then we have to multiply the value of the numeral by the number of times it is repeated. A symbol cannot be repeated more than three times in series.

Example:

II = 1 x 2 = 2

XX = 10 x 2 = 20

III = 1 x 3 = 3

We cannot express 4 as IIII. Because the symbol cannot be repeated more than three times.

Addition Rule:

If a smaller number is located to the right of a larger number, then you need to add numbers.

Example:

VII = 5 + 1 + 1 = 7

VIII = 5 + 1 + 1 + 1 = 8

XXII = 10 + 10 + 1 + 1 = 22

Subtraction Rule:

Writing a smaller number to the left side of a larger number means that the smaller number has to be subtracted from the larger number. The symbol I can be subtracted from V and X and X can be subtracted from L and C.

Example:

IV = 5 – 1 = 4

IL = 50 – 1 = 49

We do not repeat V twice to get 10. We already have a symbol for 10. So VV for writing 10 is not correct.

We do not subtract 5 from any symbol. VX is not correct.

Roman Numerals Questions with Solutions

Example 1:

Write the Roman Numerals for 57.

Solution:

The given decimal number is 57

Break up the number into Tens and Ones.

57 = 50 + 7

The symbol for 50 is L

7 = 5 + 2 = 5 + 1 + 1

The symbol for 7 is VII.

57 convert roman numerals as LVII.

Example 2:

Write the number for XXIV.

Solution:

Given roman numeral is XXIV

V = 5

IV = 5 – 1 = 4

X = 10

XX = 10 + 10 = 20

Therefore, XXIV = 20 + 4

XXIV = 24.

Example 3:

Write the Roman Numerals for 18.

Solution:

The given decimal number is 18.

Break up the number into Tens and Ones.

18 = 10 + 8

The symbol for 10 is X.

8 = 5 + 1 + 1 + 1

The symbol for 5 is V, 1 is I

So, the symbol for 8 is VIII

18 convert roman numerals as XVIII.

Example 4:

Write the number for XXXIX.

Solution:

Given roman numeral is XXXIX

X = 10

IX = 10 – 1 = 9

XXX = 10 x 3 = 30

Therefore, XXXIX = 30 + 9 = 39

FAQs on Roman Numerals

1. How do you write roman numerals?
Roman numerals can be written by using seven different alphabets. They are I for 1, V for 5, X for 10, L for 50, C for 100, D for 500, M for 1000. By using these symbols, you can write all roman numerals easily.

2. How to evaluate 550 in roman numerals?

550 = 500 + 50

500 = D, 50 = L

Therefore, 550 = DL.
