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, often use Roman Numerals. Have you noticed these names and wondered what these symbols (I and II) represented?
Those are Roman Numerals. Earlier, people used 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 DCCCXXXVIII to represent 838: D is 500, CCC is 300, 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 up to three times. For example, XXX → 30.
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. For 8, we write VIII, not IIIIIIII.
Let’s now learn how to write 838 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 838 in Roman numerals using the expansion method.
To write 838 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.
For 838, we write it as 800 + 30 + 8.
Step 2: Convert the number into Roman Numerals
800 in Roman Numerals — DCCC
30 in Roman Numerals — XXX
8 in Roman Numerals — VIII
Step 3: Combine the Roman Numerals together.
Therefore, 838 in Roman Numerals is DCCC (800) + XXX (30) + VIII (8) = DCCCXXXVIII
When writing a large number into Roman Numerals, we group the number.
To write 838 in Roman Numerals, we group 838 as 800 + 30 + 8.
800 in Roman Numerals — DCCC
30 in Roman Numerals — XXX
8 in Roman Numerals — VIII
So, 838 is written as DCCCXXXVIII in Roman Numerals.
Calculate the sum of DCCC and XXXVIII.
A museum has displayed DCCCXXXVIII artifacts over XLIV rooms. How many artifacts are in each room on average?
If you subtract CCL from DCCCXXXVIII, what is the result?
A historian is cataloging ancient coins and finds that the sum of two collections is DCCCXXXVIII. If one collection is CLXXV, how many coins are in the second collection?
Convert the number 838 into Roman Numerals using the breakdown method.
