70 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. 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 LXX to represent 70, here L is 50 and XX is 20. 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, LXX → L + X + X → 50 + 10 + 10 = 70

Rule 2: Repetition Method

To write a large number, certain Roman Numerals can be repeated up to three times. For example, XXX → 30.

Rule 3: Subtraction Method

If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40

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 won't write LL for 100; instead, we use C.

Let’s now learn how to write 70 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 70 in Roman numerals using the expansion method.

To write 70 in Roman Numerals, follow the steps:

Step 1: The number is broken down based on the place value. Place value that is tens, hundreds, etc.

For 70, we write it as 50 + 20

Step 2: Converting the number into Roman Numerals

    50 in Roman Numeral — L
    20 in Roman Numeral — XX

Step 3: Combining the Roman Numerals together.

Therefore, 70 in Roman Numeral is L (50) + XX (20) = LXX

When writing a large number into Roman Numeral, we group the number. 

To write 70 in Roman Numeral, we group 70 as 50 + 20

50 in Roman Numeral — L

20 in Roman Numeral — XX

So, 70 is written as LXX 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 70:

• Addition rule: The addition method is used when a large number is followed by a smaller numeral, here the values are added. For example, LXX = L + X + X = 50 + 10 + 10 = 70.

• Grouping method: Here the given numbers are grouped based on their place value, and then we convert each group into its Roman numerals. For example, 70 = 50 + 20 = LXX.

• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent the number 30).

• Subtraction rule: The subtraction method is used when a smaller numeral precedes a larger one. For example, XL = L - X = 50 - 10 = 40.

• Limitation rule: Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated.
