Roman numerals are a 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 the 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 CXCIV to represent 194, here C is 100, XC is 90, and IV is 4. 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 larger number, certain Roman Numerals can be repeated up to three times. III → 3.
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; this is the subtraction method. 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.
Let’s now learn how to write 194 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
By Expansion Method
By Grouping Method
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 194 in Roman numerals using the expansion method.
To write 194 in Roman Numerals, follow the steps:
Step 1: The number is broken based on the place value. Place values are ones, tens, hundreds, etc.
For 194, we write it as 100 + 90 + 4.
Step 2: Converting the number into Roman Numerals:
- 100 in Roman Numerals — C
- 90 in Roman Numerals — XC
- 4 in Roman Numerals — IV
Step 3: Combining the Roman Numerals together:
Therefore, 194 in Roman Numerals is C (100) + XC (90) + IV (4) = CXCIV.
When writing a large number into Roman Numerals, we group the number.
To write 194 in Roman Numerals, we group 194 as 100 + 90 + 4.
- 100 in Roman Numerals — C
- 90 in Roman Numerals — XC
- 4 in Roman Numerals — IV
So, 194 is written as CXCIV in Roman Numerals.
