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 VIII or Elizabeth II, often use Roman numerals. Have you noticed these symbols and wondered what they represented?
Those are Roman Numerals. Ancient Romans developed this system for counting. 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 DCCCXXXVI to represent 836. Here, D is 500, CCC is 300, XXX is 30, and VI is 6. 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, VI → V + I → 5 + 1 = 6.
To write larger numbers, certain Roman Numerals can be repeated up to three times. CCC → 300 (C repeated three times).
If a smaller number precedes a larger number, it is subtracted. For example, IX → X - I → 10 - 1 = 9.
Symbols cannot be repeated more than three times, and symbols like V, L, and D cannot be repeated. For example, we won't write VV for 10; instead, we use X.
Let’s now learn how to write 836 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 836 in Roman numerals using the expansion method.
To write 836 in Roman Numerals, follow the steps:
Step 1: Break down the number based on place value: hundreds, tens, and ones.
For 836, we write it as 800 + 30 + 6.
Step 2: Convert each number into Roman Numerals:
800 in Roman Numerals — DCCC
30 in Roman Numerals — XXX
6 in Roman Numerals — VI
Step 3: Combine the Roman Numerals together.
Therefore, 836 in Roman Numerals is DCCC + XXX + VI = DCCCXXXVI.
When writing a large number into Roman Numerals, we group the number.
To write 836 in Roman Numerals, we group 836 as 800 + 30 + 6.
800 in Roman Numerals — DCCC
30 in Roman Numerals — XXX
6 in Roman Numerals — VI
So, 836 is written as DCCCXXXVI in Roman Numerals.
Students often make mistakes when writing numbers in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
A historian finds a document dated DCCCXXXVI years ago. How many centuries and years ago was that?
The document was dated 8 centuries and 36 years ago.
To find the centuries and years, divide 836 by 100.
DCCCXXXVI = 836
836 ÷ 100 = 8 remainder 36
Therefore, it was 8 centuries and 36 years ago.
In a museum, there are MCMXLIV artifacts, and each display case can hold DCCCXXXVI artifacts. How many full display cases are needed?
Two full display cases are needed.
To find out how many full display cases are needed, divide the total number of artifacts by the capacity of one display case.
MCMXLIV = 1944
DCCCXXXVI = 836
1944 ÷ 836 = 2.325
Since only full display cases are counted, 2 full display cases are needed.
A library collection starts with DCCCXXXVI books and adds another DLXVII books. How many books are in the collection now?
There are now MCCCIII books in the collection.
To find the total number of books, add the two quantities together.
DCCCXXXVI = 836
DLXVII = 567
836 + 567 = 1403
1403 in Roman Numerals is MCCCIII.
Convert the sum of CCCXX and DCCCXXXVI into Roman Numerals.
The sum of CCCXX and DCCCXXXVI is MCLVI.
To find the sum, add the two numbers together.
CCCXX = 320
DCCCXXXVI = 836
320 + 836 = 1156
1156 in Roman Numerals is MCLVI.
A scholar needs to subtract CCCLXXVIII from DCCCXXXVI. What is the result in Roman Numerals?
The result of the subtraction is CDLIV.
To find the result, subtract the smaller number from the larger number.
DCCCXXXVI = 836
CCCLXXVIII = 378
836 - 378 = 458
458 in Roman Numerals is CDLIV.
