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. 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. to count. 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 CX to represent 110, where C is 100 and X is 10. 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, CX → C + X → 100 + 10 = 110
Rule 2: Repetition Method
To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, XXX → 30.
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 for 8 we write VIII, not IIIIIIII.
Let’s now learn how to write 110 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 110 in Roman numerals using the expansion method.
To write 110 in Roman Numerals, follow these steps:
Step 1: Break the number based on the place value. Place value includes ones, tens, hundreds, etc.
For 110, we write it as 100 + 10
Step 2: Convert the number into Roman Numerals
100 in Roman Numerals — C
10 in Roman Numerals — X
Step 3: Combine the Roman Numerals together.
Therefore, 110 in Roman Numerals is C (100) + X (10) = CX
When writing a large number in Roman Numerals, we group the number.
To write 110 in Roman Numerals, we group 110 as 100 + 10
100 in Roman Numerals — C
10 in Roman Numerals — X
So, 110 is written as CX in Roman Numerals.
