DCCIII in Roman Numerals
To meet their daily commerce and administration needs, the ancient Romans developed Roman Numerals. It used a combination of seven symbols — I, V, X, L, C, D, and M to represent numbers. Roman numerals were used to record transactions, keep track of data, and label military units. In this topic, we are going to learn about the Roman numeral DCCIII.
What is DCCIII in Roman Numerals?
Ancient Romans discovered that counting fingers could get very complicated after 10. So to overcome the complexity, the Roman numeric system was developed. This was widely used throughout Europe as a standard writing system until the late Middle Ages.
Seven symbols are used to represent numbers in the Roman numeric system — I, V, X, L, C, D, and M. The numerals are made up of different combinations of these symbols. DCCIII in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e. DCCIII = 703.
Let us learn more about the Roman numeral DCCIII, how we write it, the mistakes we usually make, and ways to avoid these mistakes.
Basic Rules for DCCIII in Roman Numerals
When writing Roman numerals, there are a few rules that we need to follow based on the Roman numerals we are trying to write. In this section, we will learn about the rules when writing Roman numerals and how to represent them.
Rule 1: Addition Method:
When a larger symbol is followed by a smaller symbol, we add the numerals to each other. For example, in VIII, we have 5 + 3 = 8.
Rule 2: Repetition Method:
A symbol that is repeated three times in continuation increases the value of the numeral. For example, XXX = 30.
Rule 3: Subtraction Method:
We use the subtraction method when a larger symbol follows a smaller symbol. For example, XL = 40 (which is 50 – 10).
Rule 4: Limitation Rule:
Symbols cannot be repeated more than three times, and some symbols, such as V, L, and D cannot be repeated more than once. For example, 10 is represented as X and not VV.
How to Write DCCIII in Roman Numerals?
Let us learn about how to write DCCIII in Roman numerals. There are two methods that we can use to write Roman numerals:
- By Expansion Method
- By Grouping Method
DCCIII in Roman Numeral by Expansion Method
The breaking down of Roman numerals into parts and then converting them into numerals is what we call the expansion method. The expansion method is the breaking down of Roman numerals into numerical form and adding them to get the final number.
Step 1: Break the Roman numerals into parts.
Step 2: Now write each of the Roman numerals with its numerical digit in the place value.
Step 3: Add the numerals together.
For DCCIII,
Step 1: First we break the Roman numerals. DCCIII = D + C + C + I + I + I
Step 2: Write the Roman Numerals for each part The Roman Numeral D is 500 The Roman Numeral C is 100 The Roman Numeral I is 1
Step 3: Combine all the numbers D + C + C + I + I + I = 500 + 100 + 100 + 1 + 1 + 1 = 703. Therefore, the Roman Numeral DCCIII is 703.
DCCIII in Roman Numeral by Grouping Method
Using subtraction and addition rules, we will apply the grouping method. This means we break the Roman numerals into smaller groups, which makes it easier to work with. This method groups the Roman numerals logically, and then we write the numbers for each group.
Step 1: Take the largest number and write the number for that Roman numeral.
Step 2: Write the Roman numeral using the subtraction and addition rules.
Example: Let’s take the Roman numeral DCCIII.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are DCC and III. The numeral for DCC is 700.
Step 2: Now we need to either add or subtract the smaller number, depending on its place.
Here we add III to DCC and we will get DCCIII. The Roman numeral III is 3. Therefore, the numeral of DCCIII is 703.

Common Mistakes and How to Avoid Them in DCCIII Roman Numerals
Students can make mistakes when studying Roman numerals. Here are a few common mistakes students make, and ways to avoid them.
Mistake 1
Mistakes when applying the repetition method
It can be quite confusing for beginners to remember that Roman Numerals cannot be repeated more than three times. Another thing to keep in mind is that Roman Numerals such as V, L, and D cannot be repeated.
For example, writing LL as 100 is incorrect, the correct answer is C.
Mistake 2
Not subtracting the numerals correctly
The subtraction method is used when a smaller symbol follows a larger symbol. One should also remember that only specific symbols can be subtracted, like I and X.
For example, IL instead of XLIX for the number 49.
Mistake 3
Not grouping the numbers correctly.
When writing Roman numerals, we need to group the numbers correctly.
For example, the number 15, 10(X) + 5(V).
Mistake 4
Confusing similar-looking symbols for other numbers
Certain numerals have different numbers when placed in a different order. So we must make sure to fully understand the order of certain symbols and their placements. All symbols have to be placed in a different order to represent the correct number.
For example, IV(4) and VI(6) have the same symbols but are in different orders.
Mistake 5
Not counting all numbers when writing in Roman numerals.
Forgetting to count all numbers, when doing the expansion method or grouping method, can lead to mistakes.
For example, writing DCC (700) and forgetting III (3) for 703. Recheck steps once done during any arithmetic operation.
DCCIII in Roman Numerals Examples
Problem 1
Convert DCCIII into its decimal form.
In decimal form, DCCIII is 703.
Explanation
Break DCCIII into components:
D = 500
CC = 200 (C + C)
III = 3 (I + I + I)
Add values: 500 + 200 + 3 = 703
Problem 2
What is the sum of DCCIII and CCL? Provide the answer in Roman numerals.
The sum is CMCLIII.
Explanation
Convert both Roman numerals into their decimal form:
DCCIII = 703
CCL = 250
Now add the numbers: 703 + 250 = 953
Convert 953 into Roman numerals: 900 (CM) + 50 (L) + 3 (III) = CMCLIII
Problem 3
Subtract CCCX from DCCIII. Write the result in Roman numerals.
The result is CDXCIII.
Explanation
Convert the Roman numerals to decimal form:
DCCIII = 703
CCCX = 310
Subtract the numbers: 703 - 310 = 393
Convert 393 into Roman numerals: 300 (CCC) + 90 (XC) + 3 (III) = CDXCIII
Problem 4
Multiply DCCIII by 2. What is the result in Roman numerals?
The result is MCDVI.
Explanation
Convert DCCIII to decimal form:
DCCIII = 703
Multiply by 2: 703 × 2 = 1406
Convert 1406 into Roman numerals: 1000 (M) + 400 (CD) + 6 (VI) = MCDVI
Problem 5
Divide DCCIII by VII. Provide the result in Roman numerals.
The result is C.
Explanation
Convert DCCIII and VII to decimal form:
DCCIII = 703
VII = 7
Divide the numbers: 703 ÷ 7 = 100
Convert 100 into Roman numerals: 100 = C

Important Glossaries for DCCIII in Roman Numerals
- Limitation Rule: There are some symbols that cannot be repeated more than once (V, L, D). For example, LVV for 60 is wrong, the correct answer is LX.
- Place Value: The position of a digit in a number, this position determines its value. For example, the number 7 in 703 is in the hundred's place.
- Prime Number: A number that has only two factors or multiples is called a prime number. For example, 5 is a prime number that has only two factors 1 and itself.
- Subtraction Method: When a smaller numeral precedes a larger numeral, it is subtracted. For example, IV = 4 (5 - 1).
- Addition Method: When a smaller numeral follows a larger or equal numeral, it is added. For example, VI = 6 (5 + 1).
