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.
Royal titles, such as Henry I, Henry II, and so on, often include Roman Numerals. Have you noticed these symbols (I and II) and wondered what they represented? Those are Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc. When life became 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 CCLII to represent 252. Here, C is 100, L is 50, and II is 2. 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, CCLII → C + C + L + II → 100 + 100 + 50 + 2 = 252
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 small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large 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 won't write VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 252 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 252 in Roman numerals using the expansion method.
To write 252 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place value is ones, tens, hundreds, etc.
For 252, we write it as 200 + 50 + 2.
Step 2: Converting the number into Roman Numerals
200 in Roman Numerals — CC
50 in Roman Numerals — L
2 in Roman Numerals — II
Step 3: Combine the Roman Numerals together.
Therefore, 252 in Roman Numerals is CC (200) + L (50) + II (2) = CCLII
When writing a large number into Roman Numerals, we group the number.
To write 252 in Roman Numerals, we group 252 as 200 + 50 + 2:
200 in Roman Numerals - CC
50 in Roman Numerals - L
2 in Roman Numerals - II
So, 252 is written as CCLII in Roman Numerals.
