Roman numerals are the way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman Numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman Numerals, rules, and examples.
The royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc. When life became complex, a standard form was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.
In Roman Numerals, we use CCXXVI to represent 226, where C is 100, X is 10, and VI is 6. 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.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, VI → V + I → 5 + 1 = 6.
Rule 2: Repetition Method
To write a large number, there are certain Roman Numerals that can be repeated three times. CCC → 300.
Rule 3: Subtraction Method
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, IX → X - I → 10 - 1 = 9.
Rule 4: Limitation Rule
The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won't write VV for 10; instead, we use X, and 8 we write as VIII, not IIIIIIII.
Let’s now learn how to write 226 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 226 in Roman numerals using the expansion method.
To write 226 in Roman Numerals, follow these steps:
Step 1: Break the number based on the place value. Place value that is ones, tens, hundreds, etc.
For 226, we write it as 200 + 20 + 6.
Step 2: Converting the number into Roman Numerals
200 in Roman Numeral — CC
20 in Roman Numeral — XX
6 in Roman Numeral — VI
Step 3: Combine the Roman Numerals together.
Therefore, 226 in Roman Numerals is CC + XX + VI = CCXXVI.
When writing a large number into Roman Numerals, we group the numbers.
To write 226 in Roman Numerals, we group 226 as 200 + 20 + 6.
200 in Roman Numeral — CC
20 in Roman Numeral — XX
6 in Roman Numeral — VI
So, 226 is written as CCXXVI in Roman Numerals.
Students make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
A historian is transcribing a parchment that mentions the year CCXXVI followed by the year CCL. How many years passed between the two years?
The number of years between CCXXVI and CCL is XXIV.
To find the difference in years, subtract CCXXVI from CCL.
CCXXVI = 226
CCL = 250
Difference: 250 226 = 24
24 in Roman numerals is XXIV.
A museum exhibits CCXXVI artifacts, and they want to distribute them equally into XIII different categories. How many artifacts will go into each category?
Each category will receive XVII artifacts.
To find the number of artifacts per category, divide CCXXVI by XIII.
CCXXVI = 226
XIII = 13
Division: 226 / 13 = 17
Add the additional windows to the existing number:
CCXXVI = 226
IX = 9
Sum: 226 + 9 = 235
235 in Roman numerals is CCXXXV.
17 in Roman numerals is XVII.
An architect is designing a building with CCXXVI windows and plans to add IX more. What will be the total number of windows?
The total number of windows will be CCXXXV.
NA
A researcher notes that a certain event occurred in the year CCXXVI and another event occurred CL years earlier. What was the earlier year?
The earlier year was LXXVI.
Subtract CL from CCXXVI to find the earlier year:
CCXXVI = 226
CL = 150
Difference: 226 150 = 76
76 in Roman numerals is LXXVI.
Convert the sum of 226 and 37 into Roman numerals using the expansion method.
The Roman numeral for 226 + 37 is CCLXIII.
Step 1: Convert the numbers 226 and 37 into Roman numerals:
226 = CCXXVI
37 = XXXVII
Add the numbers together:
226 + 37 = 263
Using the expansion method:
263 = 200 + 60 + 3 = CCLXIII
