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 MXXIV.
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. MXXIV in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e., MXXIV = 1024.
Let us learn more about the Roman numeral MXXIV, 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 smaller symbol precedes a larger 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 MXXIV 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 MXXIV,
Step 1: First, we break the Roman numerals. MXXIV = M + X + X + IV
Step 2: Write the Roman Numerals for each part The Roman Numeral M is 1000 The Roman Numeral X is 10 The Roman Numeral IV is 4
Step 3: Combine all the numbers M + X + X + IV = 1000 + 10 + 10 + 4 = 1024. Therefore, the Roman Numeral MXXIV is 1024.
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 MXXIV.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are M, XX, and IV. The numeral for M is 1000 The numeral for XX is 20
Step 2: Now we need to either add or subtract the smaller number, depending on its place.
Here we add XX and IV to M and we will get MXXIV. The Roman numeral IV is 4 Therefore, the numeral of MXXIV is 1024.
Students can make mistakes when studying Roman numerals. Here are a few common mistakes students make, and ways to avoid them.
If an ancient artifact is marked with the year MXXIV and another is marked with the year DCCLIV, calculate the combined age of both artifacts in Roman numerals, given that the current year is MMXXIII.
The combined age is MMMCDXCIX.
First, convert the Roman numerals to decimal form:
MXXIV = 1024
DCCLIV = 754
Calculate the age of each artifact: MMXXIII - MXXIV = 999
MMXXIII - DCCLIV = 1269
Now, add their ages: 999 + 1269 = 2268
Convert 2268 into Roman numerals: 2000 (MM) + 200 (CC) + 60 (LX) + 8 (VIII) = MMCCLXVIII
A historian finds two scrolls dated MXXIV and MCXV. What is the difference in years between the two scrolls in Roman numerals?
The difference is CMIX.
Convert both Roman numerals to decimal:
MXXIV = 1024
MCXV = 1115
Subtract the earlier date from the later one: 1115 - 1024 = 91
Convert 91 into Roman numerals: 90 (XC) + 1 (I) = XCI
A scholar needs to divide the number MXXIV by VIII. What is the result in Roman numerals?
The result is CXXVIII.
Convert MXXIV into its decimal form:
MXXIV = 1024
Divide 1024 by 8: 1024 / 8 = 128
Convert 128 into Roman numerals: 100 (C) + 20 (XX) + 8 (VIII) = CXXVIII
Calculate the product of M and XXIV in Roman numerals.
The product is XXIV.
Convert M and XXIV to decimal numbers:
M = 1000
XXIV = 24
Calculate the product: 1000 × 24 = 24000 Convert 24000 to Roman numerals: Since standard Roman numerals do not typically represent numbers this large, the product would be expressed using a notation involving lines or parentheses.
However, in this example, the Roman numeral representation of such a large number is not typically encountered in standard numeral systems.
Convert MXXIV into its decimal form.
In decimal form, MXXIV is 1024.
Break MXXIV into components:
M = 1000
XX = 20 (X + X)
IV = 4 (V - I)
Add values: 1000 + 20 + 4 = 1024
