Roman numerals are a way of expressing numbers using specific symbols: I, V, X, L, C, D, and M. These numerals are prevalent in royal titles, book names, sequences, and more. Here we will discuss Roman numerals, rules, and examples.
What is 143 in Roman Numerals?
Royal titles such as Henry I, Henry II, and so on use Roman numerals to denote the order. Roman numerals originated when ancient Romans needed a standard form of counting as life became more complex. 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, 143 is written as CXLIII: C is 100, XL is 40 (50 10), and III is 3. Let’s learn more about Roman numerals and how we write them.
Basic Rules for 143 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 a smaller number is placed after a larger number. For example, CXLIII → C + XL + III → 100 + 40 + 3 = 143.
Rule 2: Repetition Method
To represent certain numbers, some Roman numerals can be repeated up to three times. For example, III → 3.
Rule 3: Subtraction Method
If a smaller number precedes a larger number, it is subtracted. For example, XL → L X → 50 10 = 40.
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 won't write CCCC for 400; instead, we use CD.
