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 MC.
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. MC in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e., MC = 1100.
Let us learn more about the Roman numeral MC, 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 VI, we have 5 + 1 = 6.
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, CD = 400 (which is 500 – 100).
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 MC 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 MC,
Step 1: First we break the Roman numerals. MC = 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 + C = 1000 + 100 = 1100. Therefore, the Roman Numeral MC is 1100.
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 MC.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are M and C. The numeral for M is 1000.
Step 2: Now we need to either add or subtract the smaller number, depending on its place.
Here we add C to M and we will get MC. The Roman numeral C is 100. Therefore, the numeral of MC is 1100.
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 MC + D. Express your answer in Roman numerals.
The sum is MD
Convert both Roman numerals into their decimal form:
MC = 1100
D = 500
Add the numbers: 1100 + 500 = 1600
Convert 1600 into Roman numerals: 1600 = 1000 (M) + 500 (D) + 100 (C) = MD
Subtract LXXV from MC. Provide your answer in Roman numerals.
The difference is CMXXV
Convert the Roman numerals into their decimal form:
MC = 1100
LXXV = 75
Subtract the numbers: 1100 - 75 = 1025
Convert 1025 into Roman numerals: 1000 (M) + 20 (XX) + 5 (V) = CMXXV
Divide MC by V and express the result in Roman numerals.
CCXX
Convert MC into its decimal form:
MC = 1100
Divide by 5: 1100 / 5 = 220
Convert 220 into Roman numerals: 200 (CC) + 20 (XX) = CCXX
Find the product of MC and II. Write your answer using Roman numerals.
MMCC
Convert MC and II into numbers:
MC = 1100
II = 2
Multiply the numbers: 1100 × 2 = 2200
Convert 2200 into Roman numerals: 2000 (MM) + 200 (CC) = MMCC
Convert MC into its decimal form.
In decimal form, MC is 1100
Break down MC into components:
M = 1000
C = 100
Add the values: 1000 + 100 = 1100
