FAQs on CXXIV Roman Numerals
To write CXXIV Roman numerals in numbers, we can use two different methods.
I. Expansion Method
II. Grouping Method
Break the CXXIV Roman numerals into parts.
Replace each Roman numeral with its numerical value as per place value.
Add all of these numbers together.
In this method, we have to first write CXXIV in expanded form as C + X + X + (V – I)
and then add/subtract each number individually. i.e.,= 100 + 10 + 10 + 4 = 124
In the second method, we can pair numbers in groups and then consider them for addition/subtraction.
For instance, CXXIV can be written in groups as
C + XX + IV
Now, replace each numeral with its numerical value and add: 100 + 20 + 4 = 124.

There are important rules that should be followed to write and convert Roman numerals into numbers correctly. They involve understanding the placement and repetition of letters and symbols. As Roman numerals apply both addition and subtraction to represent numbers, it’s essential to follow the fundamental rules that govern Roman numeral construction to ensure accuracy.
No numeral can appear more than three times in a row (e.g., XX = 20, but 4 is IV).
Smaller numerals before larger ones indicate subtraction (e.g., IX = 9).
Smaller numerals after larger ones indicate addition (e.g., VI = 6).
Only certain pairs use the subtraction rule, such as:
I before V and X
X before L and C
These basic rules help avoid common mistakes when writing Roman numerals.
Answer: To write CXXIV Roman numeral in numerical value, we first need to break it into smaller parts and then add them as: C + X + X + (V – 1) = 100 + 10 + 10 + (5 - 1) = 124
Answer: We know that,
CXXIV = C + X + X + IV = 100 + 10 + 10 + 4 =124
CXX = C + X + X = 100 + 10 + 10 = 120
So, CXXIV – CXX = 124 –120 = 4
Therefore, CXXIV – CXX = IV
Answer: C = 100 and XXIV = 24, So, C + XXIV = CXXIV.
Roman numbers are part of an ancient number system that is still in use. It originated in ancient Rome. It uses a combination of letters and specific rules for addition and subtraction to write numbers. By learning these rules and practicing examples, students can easily interpret the Roman numerals in daily life.
1. Write the numerical value of CXXIV Roman numeral.
Answer: To write CXXIV Roman numeral in numerical value, we first need to break it into smaller parts and then add them as: C + X + X + X + IV = 100 + 10 + 10 + 4 = 124
2. Determine the value of CXX + VI.
Answer: We know that,
CXX = C + X + X = 100 + 10 + 10 =120
VI = 6
So, CXX + VI = 120 + 6 = 126
Therefore, CXX + VI = CXXVI
3. What is the sum of C + XXIV?
Answer: C = 100 and XXIV = 24, So, C + XXIV = CXXIV.
4. How to write 100, 500, and 1000 in Roman numerals?
Answer:
100 = C
500 = D
1000 = M
