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.
Royal titles, such as Henry I, Henry II, and so on, have numbers represented by Roman Numerals. Earlier, people used fingers, sticks, bones, etc., to count.
As life became complex, a standard form was required for counting, and Ancient Romans used the Roman Numeral system. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used. In Roman Numerals, we use CDXVI to represent 416.
Here, C is 100, D is 500, 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, VI → V + I → 5 + 1 = 6.
To write larger numbers, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.
If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we write 10 as X, not VV.
Let’s now learn how to write 416 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, the number is broken down based on place value. In this section, we will learn how to write 416 in Roman numerals using the expansion method. To write 416 in Roman Numerals, follow the steps:
Step 1: Break the number based on place value: hundreds, tens, and ones. For 416, we write it as 400 + 10 + 6.
Step 2: Convert each number into Roman Numerals.
400 in Roman Numerals - CD
10 in Roman Numerals - X
6 in Roman Numerals - VI
Step 3: Combine the Roman Numerals together. Therefore, 416 in Roman Numerals is CD (400) + X (10) + VI (6) = CDXVI.
When writing a large number into Roman Numerals, we group the number. To write 416 in Roman Numerals, we group 416 as 400 + 10 + 6.
So, 416 is written as CDXVI in Roman Numerals.
Calculate the sum of CD and XVI.
A historian finds a scroll detailing the lives of CXXIX individuals, each living an average of III centuries. Determine the total number of centuries described in the scroll.
A sculptor carves CDXVI statues in a year. If he works MM days a year, how many statues does he carve per day?
Find the difference between CDXL and XXIV.
Write the Roman Numeral for 216 + 200 using the expansion method.
