71 in Roman Numerals
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.
What is 71 in Roman Numerals?
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals like I and II. These symbols represent numbers. In ancient times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standardized form was required. The ancient Romans developed the Roman numeral system. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used in this system.
In Roman numerals, we use LXXI to represent 71. Here, L is 50, XX is 20, and I is 1. Let’s learn more about Roman numerals and how we write them.
Basic Rules for 71 in Roman Numerals
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, LXXI → L + XX + I → 50 + 20 + 1 = 71.
Rule 2: Repetition Method
To write a larger number, certain Roman numerals can be repeated up to three times. For example, XX → 20.
Rule 3: Subtraction Method
If a small number is followed by a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9.
Rule 4: Limitation Rule
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 LL for 100; instead, we use C.
