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 MXCII.
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. MXCII in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e. MXCII = 1092.
Let us learn more about the Roman numeral MXCII, 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 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 MXCII 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 MXCII,
Step 1: First, we break the Roman numerals. MXCII = M + XC + I + I
Step 2: Write the Roman Numerals for each part The Roman Numeral M is 1000 The Roman Numeral XC is 90 (100 - 10) The Roman Numeral I is 1
Step 3: Combine all the numbers M + XC + I + I = 1000 + 90 + 1 + 1 = 1092. Therefore, the Roman Numeral MXCII is 1092.
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 MXCII.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are M, XC, and II. The numeral for M is 1000 The numeral for XC is 90
Step 2: Now we need to either add or subtract the smaller number, depending on its place.
Here we add II to the sum of M and XC, and we will get MXCII. The Roman numeral II is 2 Therefore, the numeral of MXCII is 1092.
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 MXCII + VIII. Provide the answer in Roman numerals.
The sum is MCM.
Convert both Roman numerals into their decimal form:
MXCII = 1092
VIII = 8
Add the numbers: 1092 + 8 = 1100
Convert 1100 into Roman numerals: 1100 = 1000 (M) + 100 (C) = MCM
What is the difference between MXCII and XLIV? Provide the answer in Roman numerals.
The difference is MXLVIII.
Convert the Roman numerals into decimal form:
MXCII = 1092
XLIV = 44
Subtract the numbers: 1092 - 44 = 1048
Convert 1048 into Roman numerals: 1000 (M) + 40 (XL) + 8 (VIII) = MXLVIII
Divide MXCII by 2 and express the result in Roman numerals.
DXLVI
Convert MXCII into decimal form:
MXCII = 1092
Divide by 2: 1092 / 2 = 546
Convert 546 into Roman numerals: 500 (D) + 40 (XL) + 6 (VI) = DXLVI
Find the product of MXCII and III.
The product is MMCCCLXXVI.
Convert MXCII and III into numbers:
MXCII = 1092
III = 3
Multiply the numbers: 1092 × 3 = 3276
Convert 3276 into Roman numerals: 3000 (MMM) + 200 (CC) + 70 (LXX) + 6 (VI) = MMCCCLXXVI
Convert MXCII into its decimal form.
In decimal form, MXCII is 1092.
Break MXCII into components:
M = 1000
XC = 90 (100 - 10)
II = 2
Add values: 1000 + 90 + 2 = 1092
