Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman Numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman Numerals, rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are the Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc., but as life became more complex, a standard form was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.
In Roman Numerals we use CCCLXIII to represent 363, where CCC is 300, LX is 60, and III is 3. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules to write a number in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, LX → L + X → 50 + 10 = 60
Rule 2: Repetition Method
To write a large number, there are certain Roman Numerals that can be repeated up to three times. CCC → 300 (C is repeated three times).
Rule 3: Subtraction Method
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9
Rule 4: Limitation Rule
The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, instead of VV for 10, we use X, and instead of IIIIIIII for 8, we write VIII.
Let’s now learn how to write 363 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
By Expansion Method
By Grouping Method
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 363 in Roman numerals using the expansion method.
To write 363 in Roman Numerals, follow the steps,
Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc.
For 363, we write it as 300 + 60 + 3.
Step 2: Converting the number into Roman Numerals
300 in Roman Numerals — CCC
60 in Roman Numerals — LX
3 in Roman Numerals — III
Step 3: Combining the Roman Numerals together.
Therefore, 363 in Roman Numerals is CCC (300) + LX (60) + III (3) = CCCLXIII
When writing a large number into Roman Numerals, we group the number.
To write 363 in Roman Numerals, we group 363 as 300 + 60 + 3.
300 in Roman Numerals — CCC
60 in Roman Numerals — LX
3 in Roman Numerals — III
So, 363 is written as CCCLXIII in Roman Numerals.
Find the quotient when CCCLXIII is divided by III.
A historian cataloged CCCLXIII artifacts and wants to distribute them equally into VI collections. How many artifacts will be in each collection?
Find the sum of CLX and CCIII.
What is the difference between CCCLXXX and XVII.
Write the Roman Numeral for 200 + 163 using the expansion method.
