Basic Writing Rules

• It is forbidden to use more than three identical symbols in a row (exception - the letter M in classic notation)
• Subtraction is only possible for numbers that differ by 10 or 5:
• I is subtracted only from V and X (IV = 4, IX = 9)
• X is subtracted only from L and C (XL = 40, XC = 90)
• C is subtracted only from D and M (CD = 400, CM = 900)

Numbers Above 3999

Example of converting number 4,324:

           4,000 → ĪV̄
           300 → CCC
           20 → XX
           4 → IV
       

Result: ĪV̄CCCXXIV

Historical Features

• In ancient Rome, various notations were used for large numbers
• The system using vinculum (horizontal line above) was standardized in the Middle Ages
• Sometimes double and triple vincula were used above to indicate multiplication by 1,000,000 and 1,000,000,000

Important Notes:

• The vinculum system allows for compact notation of very large numbers
• Not all fonts support symbols with macron
• In modern usage, numbers up to 3999 are most common
• When working with large numbers, it's important to consider the context of use and display capabilities
