Roman numerals are a way of expressing numbers using symbols. The symbols used are I, V, X, L, C, D, and M. Roman numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman numerals, rules, and examples.
Royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman numerals. Earlier people counted using fingers, sticks, bones, etc. As life became more complex, a standard form was required for counting. Ancient Romans used the Roman numeral system to count. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used.
In Roman numerals, we use CCCLIII to represent 353. Here, CCC is 300, L is 50, 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 a smaller number is placed after a larger number. For example, CCCLIII → CCC + L + III → 300 + 50 + 3 = 353.
Rule 2: Repetition Method
To write a large number, certain Roman numerals can be repeated up to three times. For example, III → 3.
Rule 3: Subtraction Method
If a smaller number is followed by a larger 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, we wouldn't write LL for 100; instead, we use C.
Let’s now learn how to write 353 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 353 in Roman numerals using the expansion method.
To write 353 in Roman numerals, follow these steps:
Step 1: Break the number based on place value. The place values are hundreds, tens, and ones.
For 353, we write it as 300 + 50 + 3.
Step 2: Convert the numbers into Roman numerals.
300 in Roman numeral — CCC
50 in Roman numeral — L
3 in Roman numeral — III
Step 3: Combine the Roman numerals together.
Therefore, 353 in Roman numeral is CCC (300) + L (50) + III (3) = CCCLIII.
When writing a large number in Roman numerals, we group the numbers.
To write 353 in Roman numerals, we group it as 300 + 50 + 3.
300 in Roman numeral — CCC
50 in Roman numeral — L
3 in Roman numeral — III
Therefore, 353 is written as CCCLIII in Roman numerals.
