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 MMMC.
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. MMMC in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e. MMMC = 3100.
Let us learn more about the Roman numeral MMMC, how we write them, 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 XIII, we have 10 + 3 = 13.
A symbol that is repeated three times in continuation increases the value of the numeral. For example, CCC = 300.
We use the subtraction method when a larger symbol follows a smaller symbol. For example, XC = 90 (which is 100 – 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, 15 is represented as XV and not VVV.
Let us learn about how to write MMMC 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 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 MMMC,
Step 1: First we break the Roman numerals. MMMC = M + M + M + C
Step 2: Write the Roman Numerals for each part The Roman Numeral M is 1000 The Roman Numeral C is 100
Step 3: Combine all the numbers M + M + M + C = 1000 + 1000 + 1000 + 100 = 3100. Therefore, the Roman Numeral MMMC is 3100.
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 MMMC.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are MMM and C. The numeral for MMM is 3000
Step 2: Now we need to add the smaller number.
Here we add C to MMM and we will get MMMC. The Roman numeral C is 100 Therefore, the numeral of MMMC is 3100.
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 MMC + MC. Write the answer in Roman numerals.
The sum is MMMC
Convert both Roman numerals into their decimal form:
MMC = 2100
MC = 1100
Now add both numbers: 2100 + 1100 = 3200
Now convert the number into its Roman numeral. 3200 = 3000 (MMM) + 200 (CC) = MMMC
What is the difference between MMMC and MCM? Write in Roman numerals.
The difference is MCC
Convert the Roman numerals into their decimal form:
MMMC = 3200
MCM = 1900
Now we subtract the numbers: 3200 - 1900 = 1300
Convert the number into its Roman numeral: 1300 = 1000 (M) + 300 (CCC) = MCC
If you divide MMMC by 4, what is the result in Roman numerals?
DCCC
Convert MMMC into its decimal form:
MMMC = 3200
Divide by 4: 3200 / 4 = 800
Write 800 in Roman numerals: 800 = 500 (D) + 300 (CCC) = DCCC
What is the product of MCC and III?
MMCCC is the product of MCC and III.
Write MCC and III in numbers:
MCC = 1200
III = 3
Multiply the numbers: 1200 × 3 = 3600
Convert 3600 into its Roman numerals: 3000 (MMM) + 600 (DC) = MMCCC
Convert MMMC into its decimal form.
In decimal form, MMMC is 3200
Break MMMC into components:
MMM = 3000
C = 100
Add values: 3000 + 100 = 3200
