Roman numerals are the 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. 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 DXXXVIII to represent 538, where D is 500, XXX is 30, 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.
The addition method is used when the smaller number is placed after the larger number. For example, VIII → V + III → 5 + 3 = 8
To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3
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
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 for 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 538 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 538 in Roman numerals using the expansion method.
To write 538 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 538, we write it as 500 + 30 + 8.
Step 2: Converting the number into Roman Numerals
Step 3: Combine the Roman Numerals together. Therefore, 538 in Roman Numerals is D (500) + XXX (30) + VIII (8) = DXXXVIII
When writing a large number in Roman Numerals, we group the number. To write 538 in Roman Numerals, we group 538 as 500 + 30 + 8.
So, 538 is written as DXXXVIII in Roman Numerals.
Calculate the sum of DXXXVIII and XII.
A historian has DLX ancient coins and decides to distribute them equally among X groups. How many coins does each group receive?
Find the difference between DC and DXXXVIII.
A collector has a collection of DXXXVIII Roman artifacts. If he sells CXXIII of them, how many artifacts does he have left?
Write the Roman Numeral for 538 + 462 using the expansion method.
