Roman numerals are a method of expressing numbers using symbols. The symbols I, V, X, L, C, D, and M are used to represent numbers. Roman Numerals are utilized in various contexts such as royal titles, book names, sequences, and more. Here, we will be discussing Roman Numerals, their rules, and examples.
Have you ever seen royal titles like Henry I, Henry II, and wondered what the symbols I and II represent? These are Roman Numerals. Initially, people counted using fingers, sticks, bones, etc. As life became more complex, a standardized form was required. Ancient Romans used the Roman Numeral system for counting. The symbols used are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
In Roman Numerals, 924 is written as CMXXIV, where CM is 900 and XXIV is 24. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules to write a number in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.
The addition method is used when a smaller number is placed after a larger number. For example, XXIV → XX + IV → 20 + 4 = 24.
To express certain numbers, some Roman Numerals can be repeated up to three times. For example, XXX → 30.
If a smaller number is placed before a larger number in Roman Numerals, the smaller number is subtracted from the larger one. For example, CM → M - C → 1000 - 100 = 900.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X.
Let’s now learn how to write 924 in Roman Numerals. Follow these methods to write the number in Roman Numerals:
In the expansion method, the number is broken down based on place value. Here’s how to write 924 in Roman numerals using the expansion method:
Step 1: Break the number based on place value (hundreds, tens, ones). For 924, write it as 900 + 20 + 4.
Step 2: Convert each part into Roman Numerals:
Step 3: Combine them: Therefore, 924 in Roman Numerals is CM (900) + XX (20) + IV (4) = CMXXIV.
When writing large numbers in Roman Numerals, group the number for clarity. To write 924 in Roman Numerals, group 924 as 900 + 20 + 4:
Thus, 924 is written as CMXXIV in Roman Numerals.
Students often make mistakes when writing numbers in Roman Numerals. To master Roman Numerals, it is helpful to learn from common mistakes and how to avoid them.
A historian discovers a parchment containing a record of CMXXIV gold coins distributed equally among VIII chieftains. How many coins did each chieftain receive?
Each chieftain received CXV coins.
To find the number of coins each chieftain received, divide the total number of coins by the number of chieftains.
CMXXIV = 924 and VIII = 8.
Thus, 924 / 8 = 115.
In Roman numerals, 115 can be written as CXV.
An ancient library was said to have housed DCLXIV scrolls, and after an expansion, received an additional CCLX scrolls. What is the new total number of scrolls in the library?
The new total number of scrolls in the library is CMXXIV.
To find the total number of scrolls, add the original number and the additional scrolls.
DCLXIV = 664 and CCLX = 260.
Thus, 664 + 260 = 924, which in Roman numerals is CMXXIV.
A Roman general divided CMXXIV soldiers into XII legions for a military campaign. How many soldiers were in each legion?
Each legion had LXXVII soldiers.
To find the number of soldiers in each legion, divide the total number of soldiers by the number of legions.
CMXXIV = 924 and XII = 12.
Thus, 924 / 12 = 77.
In Roman numerals, 77 can be written as LXXVII.
A merchant recorded sales of CCCXII, CDXII, and CC in three different markets. What is the total number of sales recorded by the merchant?
The total number of sales recorded by the merchant is CMXXIV.
To find the total sales, add the sales from the three markets.
CCCXII = 312, CDXII = 412, and CC = 200.
Thus, 312 + 412 + 200 = 924, which in Roman numerals is CMXXIV.
Calculate the difference in years between a document dated MCMXIV and another dated CMXXIV.
The difference in years between the two documents is CMXC.
To find the difference in years, subtract the earlier date from the later date.
MCMXIV = 1914 and CMXXIV = 924.
Thus, 1914 - 924 = 990.
In Roman numerals, 990 can be written as CMXC.
