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.
Have you ever seen royal titles like Henry I, Henry II, and wondered what these symbols (I and II) represent? Those are Roman Numerals. In ancient times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required for counting. Ancient Romans used the Roman numeral system. 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 CCCXXVI to represent 326. Here, CCC is 300, XX is 20, and VI is 6. 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, VI → V + I → 5 + 1 = 6.
Rule 2: Repetition Method
To write a large number, certain Roman numerals can be repeated up to three times. For example, CCC → 300.
Rule 3: Subtraction Method
If a smaller number precedes 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 write 10 as X, not VV.
Let’s learn how to write 326 in Roman numerals. Follow these methods:
In the expansion method, based on the place value, the number is broken down. Here’s how to write 326 in Roman numerals using the expansion method:
Step 1: Break the number based on place value: 300 + 20 + 6.
Step 2: Convert each into Roman numerals:
- 300 in Roman numerals — CCC
- 20 in Roman numerals — XX
- 6 in Roman numerals — VI
Step 3: Combine them together: Therefore, 326 in Roman numerals is CCCXXVI.
When writing a large number into Roman numerals, we group the number. To write 326 in Roman numerals, we group it as 300 + 20 + 6.
- 300 in Roman numerals — CCC
- 20 in Roman numerals — XX
- 6 in Roman numerals — VI
So, 326 is written as CCCXXVI in Roman numerals.
A historian is studying ancient texts and finds two numbers written in Roman numerals: CLXIII and CLXIII. She wants to calculate the total of these numbers.
An architect is planning to distribute CCCXXVI bricks equally into XLVI piles. How many bricks will each pile contain?
A collector has CCCXXVI coins and decides to give CCXLVII of them to a friend. How many coins will he have left?
Calculate the difference between CCCXXVI and CCLXXVI.
Write the Roman Numeral for 326 using the expansion method.
