Roman Numerals are the symbols derived from Latin letters used by Romans for daily transactions and counting purposes. In this topic, we will learn how to write Roman Numerals and their uses.
Roman Numerals use symbols to represent number systems. Ancient Romans used the letters I, V, X, L, C, D, and M to represent their number system. The unavailability of zero at that time and the lack of other mathematical operations made Roman Numerals obsolete in recent times. For example, we write 7 as VII.
Roman numbers are used today in clocks, chapters in books, classrooms, etc. The following chart helps us to understand the numerals better.
List of Roman Numerals 1 to 10
The list of Roman Numerals provides an organized way to understand how those letters combine to represent a number. The given list starts from I (1) to X (10). Learning these numerals helps you in a deeper understanding of the numerical system. Roman Numerals from 1 to 10
Roman Numerals rely on specific symbols, and it has rules of addition and subtraction.
The basic symbols in Roman Numerals are:
I = 1
V = 5
X = 10
Using the above symbols, we can combine the Roman Numerals for the numbers easily. There are two basic methods of writing Roman Numerals, they are
Through the expansion method, we break down the numbers into ones and then convert them into numerals.
Step 1: Break the numbers into ones.
Step 2: Write Roman Numerals for each part.
Step 3: Combine all the parts to get the numerals.
Example: For the number 9.
Step 1: Break the numbers 5 + 4 = 9
Step 2: Add Roman Numerals for each part
The Roman Numeral of 5 is V.
The Roman Numeral of 4 is IV.
Step 3: Combine all the parts 5 (V) + 4 (IV) = IX.
Therefore, the Roman Numeral of 9 is IX.
Grouping method directly from the number by combining Roman Numeral symbols directly. It uses addition and subtraction rules.
Step 1: Start writing numerals for the largest number.
Step 2: Smaller numbers are either getting added or subtracted.
Following the rule of adding and subtraction is mandatory.
Addition: smaller numeral after the larger numeral.
Subtraction: smaller numeral before the large numeral.
Example: For the number 6.
Step 1: Start with the larger numbers.
While splitting, we will get 5 and 1
The Roman Numeral of 5 is V
Step 2: Add or subtract the smaller number If we add 1 to 5 it will become 6.
The Roman Numeral of 1 is I
Therefore, the Roman Numeral of 6 is VI.
Roman Numerals follow rules to make sure the number is written correctly. Here are some main rules given below
In Roman Numerals, if the smaller numeral comes after the large numeral, then we need to add their values.
Example: If the given number is VI. We can see that the number V refers to 5 and the other number refers to 1. So in this, the smaller numeral is after the large numeral, so we need to add the 5 and 1 to get the value 6.
The Roman Numeral can be repeated up to three times to increase its value. The numbers cannot be repeated after three times. Only symbols like I, X, C, and M can be repeated and V, L, and D cannot be repeated.
Example: III = 1 + 1 + 1 = 3 repeating the numeral I for the fourth time is not allowed.
If the smaller numeral comes before the large numeral, then we need to subtract the smaller numeral from the larger numeral to get the number. There are three rules in subtraction, they are, I can be subtracted from V and X.
Example: In the number IX. Here, X is the biggest numeral and I is the smallest numeral. As we see that the smaller numeral is before the larger numeral, we need to subtract to get the number. X (10) - I (1) = IX (9).
Roman Numerals are fun to learn and easy to write when you know the following tips and tricks.
It is easy to make mistakes while learning Roman Numerals, but using the following mistakes and the ways to avoid them can help you to avoid those mistakes.
Write the Roman Numerals for 8 using the breakdown method.
The Roman Numeral of 8 is VIII.
Step 1: Break the numbers into fives and ones. 8 = 5 + 3
Step 2: Add numerals to each part.
The Roman Numeral of 5 is V.
The Roman Numeral of 3 is III.
Step 3: Combine the parts 5 (V) + 3 (III) = VIII (8).
Add IV + III.
VII
Adding IV (4) and III (3) = VII (7).
Subtract X - VI.
IV
X = 10
VI = 6
10 - 6 = 4 = IV.
Write the Roman Numeral of 10.
X
The Roman Numeral of 10 is X.
Add 5 + 2 and write the answer in Roman Numeral.
VII.
5 + 2 = 7
V + II = VII.
