From I to MMM: Everything You Need to Know About Roman Numerals

Roman Numerals Made Easy: A Complete Beginner’s Guide Roman numerals look like a secret code from the ancient world, but they follow simple rules. Whether you are trying to read a clock face, understand super bowl numbers, or check book chapters, this guide will make you an expert in minutes. The 7 Basic Symbols

You only need to memorize seven letters to read any Roman numeral. Each letter represents a specific number. I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1,000 Rule 1: The Rule of Addition

When letters are placed from largest to smallest value, you simply add them together. VI = 5 + 1 = 6 XV = 10 + 5 = 15 CLXX = 100 + 50 + 10 + 10 = 170 Rule 2: The Rule of Subtraction

When a smaller letter is placed before a larger letter, you subtract the smaller value from the larger one. IV = 5 – 1 = 4 IX = 10 – 1 = 9 XL = 50 – 10 = 40 XC = 100 – 10 = 90 CD = 500 – 100 = 400 CM = 1,000 – 100 = 900

Tip: You can only subtract I, X, and C. You can never subtract V, L, or D. Rule 3: The Limit of Three

You can never repeat the same letter more than three times in a row. III = 3 XXX = 30

To write 4 or 40, you must use the subtraction rule (IV or XL) instead of writing four letters. How to Convert Numbers Step-by-Step

To translate a modern number into Roman numerals, break it down by placeholders (thousands, hundreds, tens, and ones). Example: Convert 2026 Break down the number: 2,000 + 20 + 6 Convert 2,000: MM Convert 20: XX Convert 6: VI Put it together: MMXXVI Example: Convert 94 Break down the number: 90 + 4 Convert 90: XC (100 minus 10) Convert 4: IV (5 minus 1) Put it together: XCIV
