790 in Roman Numerals

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 DCCXC to represent 790, where D is 500, CC is 200, X is 10, and C is 100. 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, DCCXC → D + CC + X + C → 500 + 200 + 10 + 100 = 790

Rule 2: Repetition Method

To write a larger number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.

Rule 3: Subtraction Method

If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, XC → C - X → 100 - 10 = 90

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 don't write DDD for 1500; instead, we use MD.

Let’s now learn how to write 790 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 790 in Roman numerals using the expansion method.

To write 790 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value: hundreds, tens, and ones. For 790, we write it as 700 + 90

Step 2: Convert the number into Roman Numerals:

• 700 in Roman Numerals - DCC
   
• 90 in Roman Numerals - XC

Step 3: Combine the Roman Numerals together. Therefore, 790 in Roman Numerals is DCC (700) + XC (90) = DCCXC

When writing a large number in Roman Numerals, we group the number. To write 790 in Roman Numerals, we group 790 as 700 + 90

• 700 in Roman Numerals - DCC
   
• 90 in Roman Numerals - XC

So, 790 is written as DCCXC in Roman Numerals.

Roman Numerals follow a certain pattern, making them look similar. In this section, we will learn some numbers related to the Roman numeral 790. 

• Addition method: Used when a large number is followed by a smaller numeral, here the values are added. For example, DCCXC = D + CC + XC = 500 + 200 + 90 = 790

• Grouping method: Here, the given numbers are grouped based on their place value and then converted into Roman numerals. For example, 790 = 700 + 90 = DCCXC

• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, CCC = 300 (C is repeated three times to represent the number 300).

• Subtraction method: Used when a smaller numeral precedes a larger numeral to indicate subtraction. For example, XC = 100 - 10 = 90

• Limitation rule: Roman Numerals have specific rules that restrict the repetition and combination of symbols, such as not repeating V, L, and D.
