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. 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 MMXVI to represent 2016, where M is 1000, 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.
The addition method is used when the smaller number is placed after the larger number. For example, XVI → X + V + I → 10 + 5 + 1 = 16
To write a larger number, certain Roman numerals can be repeated up to three times. For example, XXX → 30.
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9
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 is written as VIII, not IIIIIIII.
Let’s now learn how to write 2016 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 2016 in Roman numerals using the expansion method.
To write 2016 in Roman numerals, follow the steps:
Step 1: Break down the number based on the place value. Place values are ones, tens, hundreds, etc. For 2016, we write it as 2000 + 10 + 5 + 1
Step 2: Converting the number into Roman numerals
2000 in Roman numerals — MM
10 in Roman numerals — X
5 in Roman numerals — V
1 in Roman numerals — I
Step 3: Combine the Roman numerals together.
Therefore, 2016 in Roman numerals is MM + X + V + I = MMXVI
When writing a large number in Roman numerals, we group the number.
To write 2016 in Roman numerals, we group 2016 as 2000 + 10 + 5 + 1
2000 in Roman numerals — MM
10 in Roman numerals — X
5 in Roman numerals — V
1 in Roman numerals — I
So, 2016 is written as MMXVI in Roman numerals.
Calculate the area of a rectangle with length MMXVI and width V.
A historian is reviewing documents from the year 2016. If he reviews XL documents per day, how many days will it take to review MMXVI documents?
A marathon started in the year MMXVI. If the runners have completed MCMXVI meters, how many more meters do they need to run to complete MMXVI meters?
A digital clock displays the time as 20:16. Convert this time into Roman numerals.
Write the Roman Numeral for the sum of MMXVI and DCCC using the expansion method.
