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. 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 DIV to represent 504, where D is 500, IV is 4.
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, then it is the addition method. For example, VI → V + I → 5 + 1 = 6
To write larger numbers, certain Roman Numerals can be repeated three times. For example, III → 3.
If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number, which is the subtraction method. 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 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 504 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 504 in Roman numerals using the expansion method. To write 504 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 504, we write it as 500 + 4
Step 2: Converting the numbers into Roman Numerals
Step 3: Combining the Roman Numerals together. Therefore, 504 in Roman Numerals is D + IV = DIV
When writing a large number into Roman Numerals, we group the number. To write 504 in Roman Numerals, we group 504 as 500 + 4
So, 504 is written as DIV in Roman Numerals.
Students make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
Calculate the sum of CDLXXX and XXIV.
The sum of CDLXXX and XXIV is DIV.
To find the sum, add the two numbers together.
CDLXXX = 480
XXIV = 24
480 + 24 = 504
504 in Roman Numerals is DIV.
A historian has a collection of DXXII ancient coins and decides to give XVIII to a museum. How many coins will remain in the collection?
The number of coins remaining in the collection is DIV.
Subtract the coins given to the museum from the total collection.
DXXII = 522
XVIII = 18
522 - 18 = 504
504 in Roman Numerals is DIV.
A marathon was completed in DLXIV minutes, and a runner finished XL minutes early. How long did it take the runner to complete the marathon?
The runner completed the marathon in DIV minutes.
Subtract the early finish time from the total marathon time.
DLXIV = 564
XL = 40
564 - 40 = 524
524 in Roman Numerals is DIV.
An ancient scroll contains DXLV pages, but XII pages are missing. How many pages are present in the scroll?
The number of pages present in the scroll is DIV.
Subtract the missing pages from the total pages to find the present pages.
DXLV = 545
XII = 12
545 - 12 = 533
533 in Roman Numerals is DIV.
Write the Roman Numeral for 300 + 204 using the expansion method.
The Roman numeral for 300 + 204 is DIV.
Step 1: First convert the numbers 300 and 204 into Roman numerals.
300 - CCC
204 - CCIV
Add the numbers together: 300 + 204 = 504
Using the expansion method: 504 = 500 + 4 = DIV.
