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 DCCII.
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.
The system uses seven symbols to represent numbers — I, V, X, L, C, D, and M. The numerals are made up of different combinations of these symbols. DCCII in Roman numerals is written in number form by adding the values of each Roman numeral, i.e., DCCII = 702.
Let us learn more about the Roman numeral DCCII, how we write it, the mistakes we usually make, and ways to avoid these mistakes.
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.
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.
A symbol that is repeated three times in continuation increases the value of the numeral. For example, XXX = 30.
We use the subtraction method when a larger symbol follows a smaller symbol. For example, XL = 40 (which is 50 – 10).
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.
Let us learn about how to write DCCII in Roman numerals. There are two methods that we can use to write Roman numerals:
The breaking down of Roman numerals into parts and then converting them into numerals is what we call the expansion method. The expansion method involves breaking down Roman numerals into numerical form and adding them to get the final number.
Step 1: Break the Roman numerals into parts.
Step 2: Write each of the Roman numerals with its numerical digit in the place value.
Step 3: Add the numerals together.
For DCCII,
Step 1: First, we break the Roman numerals. DCCII = D + C + C + 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 = 500 + 100 + 100 + 1 + 1 = 702. Therefore, the Roman Numeral DCCII is 702.
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 DCCII.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are DCC and II. 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 II to DCC, and we will get DCCII. The Roman numeral II is 2. Therefore, the numeral of DCCII is 702.
Students can make mistakes when studying Roman numerals. Here are a few common mistakes students make, and ways to avoid them.
Calculate the sum of DCCII + CCL. Present your answer in Roman numerals.
The sum is CMLII
Convert both Roman numerals into decimal form:
DCCII = 702
CCL = 250
Now add both numbers: 702 + 250 = 952
Convert the result into Roman numerals: 952 = 900 (CM) + 50 (L) + 2 (II) = CMLII
What is the difference when you subtract CLIII from DCCII? Express your answer in Roman numerals.
The difference is DLXIX
Convert the Roman numerals into decimal form:
DCCII = 702
CLIII = 153
Subtract the second number from the first: 702 - 153 = 549
Convert the result into Roman numerals: 549 = 500 (D) + 40 (XL) + 9 (IX) = DLXIX
If you divide DCCII by 2, what would the result be in Roman numerals?
CCCLI
Convert DCCII into its decimal form:
DCCII = 702
Divide by 2: 702 / 2 = 351
Convert 351 into Roman numerals: 351 = 300 (CCC) + 50 (L) + 1 (I) = CCCLI
Multiply DCCII by IV and express the result in Roman numerals.
The product is MMDCCVIII
Convert the Roman numerals into decimal form:
DCCII = 702
IV = 4
Multiply the numbers: 702 × 4 = 2808
Convert 2808 into Roman numerals: 2808 = 2000 (MM) + 800 (DCCC) + 8 (VIII) = MMDCCVIII
Convert DCCII into its decimal form.
In decimal form, DCCII is 702
Break DCCII into components:
D = 500
CC = 200 (C + C)
II = 2 (I + I)
Add values: 500 + 200 + 2 = 702
