Roman numerals are a way of expressing numbers using symbols: 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.
The 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 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 LVIII to represent 58, where L is 50, V is 5, 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, LVIII → L + V + III → 50 + 5 + 3 = 58
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 small number is followed by a large number in Roman Numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40
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 LL for 100; instead, we use C. Similarly, 8 is written as VIII, not IIIIIIII
Let’s now learn how to write 58 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 58 in Roman numerals using the expansion method.
To write 58 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.
For 58, we write it as 50 + 5 + 3
Step 2: Converting the number into Roman Numerals
50 in Roman Numerals — L
5 in Roman Numerals — V
3 in Roman Numerals — III
Step 3: Combine the Roman Numerals together.
Therefore, 58 in Roman Numerals is L (50) + V (5) + III (3) = LVIII
When writing a large number into Roman Numerals, we group the number.
To write 58 in Roman Numerals, we group 58 as 50 + 5 + 3
50 in Roman Numerals — L
5 in Roman Numerals — V
3 in Roman Numerals — III
So, 58 is written as LVIII in Roman Numerals.
