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 Roman Numerals. Earlier, people used 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 used in this system.
In Roman Numerals, we use CCCLXXXVI to represent 386. Here, C is 100, L is 50, X is 10, V is 5, and I is 1. 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 a smaller number is placed after a larger number. For example, VI → V + I → 5 + 1 = 6.
Rule 2: Repetition Method
To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
Rule 3: Subtraction Method
If a smaller number is placed before a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4.
Rule 4: Limitation Rule
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 386 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 386 in Roman numerals using the expansion method.
To write 386 in Roman Numerals, follow these steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.
For 386, we write it as 300 + 80 + 6.
Step 2: Convert the number into Roman Numerals.
- 300 in Roman Numerals — CCC
- 80 in Roman Numerals — LXXX
- 6 in Roman Numerals — VI
Step 3: Combine the Roman Numerals together.
Therefore, 386 in Roman Numerals is CCC (300) + LXXX (80) + VI (6) = CCCLXXXVI.
When writing a large number into Roman Numerals, we group the number. To write 386 in Roman Numerals, we group 386 as 300 + 80 + 6.
- 300 in Roman Numerals — CCC
- 80 in Roman Numerals — LXXX
- 6 in Roman Numerals — VI
So, 386 is written as CCCLXXXVI in Roman Numerals.
A historian is researching ancient texts and finds that a library had CCCLXXXVI scrolls divided equally into II sections. How many scrolls were in each section?
An archaeologist found CCCLXXXVI pieces of pottery and wants to distribute them equally among VII teams. How many pieces will each team receive?
A museum exhibited CCXL paintings, and another museum exhibited CXLVI paintings. What is the total number of paintings exhibited?
A mathematician is decoding ancient scripts and needs to find the difference between CD and CCXIV. What is the difference?
Write the Roman numeral for 386 using the expansion method.
