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 DCXCV to represent 695, where D is 500, C is 100, X is 10, and V is 5.
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, then it is the addition method. For example, DCXCV → D + C + X + V → 500 + 100 + 10 + 5 = 695
To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number; it is a subtraction method. 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 DDD for 1500; instead, we use M and D together to form 1500 as MD.
Let’s now learn how to write 695 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 695 in Roman numerals using the expansion method. To write 695 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 695, we write it as 600 + 90 + 5.
Step 2: Converting the number into Roman Numerals
Step 3: Combining the Roman Numerals together. Therefore, 695 in Roman Numerals is DC (600) + XC (90) + V (5) = DCXCV
When writing a large number in Roman Numerals, we group the number. To write 695 in Roman Numerals, we group 695 as 600 + 90 + 5.
So, 695 is written as DCXCV in Roman Numerals.
