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.
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, XX → X + X → 10 + 10 = 20.
Rule 2: Repetition Method
To write a large number, there are certain Roman numerals that can be repeated three times. For example, CCC → 300.
Rule 3: Subtraction Method
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the large number. For example, IV → V I → 5 1 = 4.
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 won't write VV for 10; instead, we use X, and 8 we write as VIII, not IIIIIIII.
Let’s now learn how to write 224 in Roman numerals. Follow these methods to write the number in Roman numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 224 in Roman numerals using the expansion method.
To write 224 in Roman numerals, follow these steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.
For 224, we write it as 200 + 20 + 4.
Step 2: Converting each number into Roman numerals:
200 in Roman numerals — CC
20 in Roman numerals — XX
4 in Roman numerals — IV
Step 3: Combine the Roman numerals together.
Therefore, 224 in Roman numerals is CC (200) + XX (20) + IV (4) = CCXXIV.
When writing a large number in Roman numerals, we group the numbers. To write 224 in Roman numerals, we group 224 as 200 + 20 + 4:
200 in Roman numerals — CC
20 in Roman numerals — XX
4 in Roman numerals — IV
So, 224 is written as CCXXIV in Roman numerals.
