Roman numerals are a system of expressing numbers using specific symbols. The symbols used are I, V, X, L, C, D, and M. Roman numerals are often found in royal titles, book names, sequences, and more. In this guide, we will discuss Roman numerals, the rules for writing them, and examples.
In royal titles such as Henry I, Henry II, and so on, Roman numerals appear frequently. Have you ever wondered what these symbols represent? These are Roman numerals. In ancient times, people used various methods like fingers, sticks, or bones for counting.
As life became more complex, a standardized form was needed, leading to the Roman numeral system. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used in this system.
To represent 184 in Roman numerals, we use CLXXXIV. Here, C is 100, L is 50, XXX is 30, and IV is 4. Let’s learn more about Roman numerals and how we write them.
There are certain fundamental rules for writing numbers in Roman numerals. Let's explore some basic rules that need to be remembered when writing numbers in Roman numerals.
Rule 1: Addition Method
The addition method is used when a smaller numeral is placed after a larger numeral, indicating addition. For example, CLXXXIV → C + L + X + X + X + IV → 100 + 50 + 30 + 4 = 184.
Rule 2: Repetition Method
Certain Roman numerals can be repeated up to three times to represent numbers. For example, XXX → 30.
Rule 3: Subtraction Method
If a smaller numeral precedes a larger numeral, the smaller numeral is subtracted from the larger numeral. For example, IV → V - I → 5 - 1 = 4.
Rule 4: Limitation Rule
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X. Similarly, 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 184 in Roman numerals. Follow these methods to write the number in Roman numerals.
In the expansion method, a number is broken down based on place value. Here’s how to write 184 using this method:
Step 1: Break down the number based on place values: 100 (hundreds), 80 (tens), and 4 (ones).
Step 2: Convert each to Roman numerals:
100 in Roman Numerals — C
80 in Roman Numerals — LXXX
4 in Roman Numerals — IV
Step 3: Combine them into Roman numerals:
184 in Roman Numerals is C (100) + LXXX (80) + IV (4) = CLXXXIV.
When writing a large number in Roman numerals, group the numbers:
184 is grouped as 100 + 80 + 4.
100 in Roman Numerals — C
80 in Roman Numerals — LXXX
4 in Roman Numerals — IV
Thus, 184 is written as CLXXXIV in Roman numerals.
Students often make mistakes when writing numbers in Roman numerals. Here are some common mistakes and tips on how to avoid them:
A historian finds a scroll that mentions the numbers CLXXXIV and LXXII. He wants to know the sum of these two numbers in Roman numerals.
The sum of CLXXXIV and LXXII is CCLVI.
Convert the Roman numerals to numbers and add them together.
CLXXXIV = 184
LXXII = 72
184 + 72 = 256
256 in Roman Numerals is CCLVI.
An architect is designing a building with CLXXXIV windows to be evenly distributed across XLVI floors. How many windows will be on each floor?
Each floor will have IV windows.
Divide the total number of windows by the number of floors.
CLXXXIV = 184
XLVI = 46
184 / 46 = 4
4 in Roman numerals is IV.
A museum has a collection of CCXXIV artifacts, and it acquires CLXXXIV more. How many artifacts does the museum have now in Roman numerals?
The museum now has CDVIII artifacts.
Add the number of artifacts.
CCXXIV = 224
CLXXXIV = 184
224 + 184 = 408
408 in Roman numerals is CDVIII.
A treasure chest contains CLXXXIV gold coins. After a transaction, LXXXIX coins are removed. How many coins remain in Roman numerals?
The remaining number of coins is XCV.
Subtract the number of coins removed from the total.
CLXXXIV = 184
LXXXIX = 89
184 - 89 = 95
95 in Roman numerals is XCV.
Calculate the Roman numeral representation for the result of subtracting XL from CLXXXIV using the subtraction method.
The Roman numeral is CXLIV.
Convert the numbers to Roman numerals and subtract them.
CLXXXIV = 184
XL = 40
184 - 40 = 144
144 in Roman numerals is CXLIV.
