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.
The royal titles, such as Henry I, Henry II, and so on. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc. to count earlier. 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 XLVIII to represent 48, where XL is 40 and VIII is 8. 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, VIII → V + I + I + I → 5 + 1 + 1 + 1 = 8.
Rule 2: Repetition Method
To write a large number, there are certain Roman Numerals that can be repeated up to three times. 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 large 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 XXXX for 40; instead, we use XL.
Let’s now learn how to write 48 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 48 in Roman numerals using the expansion method.
To write 48 in Roman Numerals, follow the steps:
Step 1: The number is broken based on the place value. Place values are ones, tens, hundreds, etc.
For 48, we write it as 40 + 8.
Step 2: Converting the number into Roman Numerals:
40 in Roman Numerals — XL
8 in Roman Numerals — VIII
Step 3: Combining the Roman Numerals together:
Therefore, 48 in Roman Numerals is XL (40) + VIII (8) = XLVIII.
When writing a large number into Roman Numerals, we group the number.
To write 48 in Roman Numerals, we group 48 as 40 + 8.
40 in Roman Numerals — XL
8 in Roman Numerals — VIII
So, 48 is written as XLVIII in Roman Numerals.
