🔢 Roman Numerals Explained:

• Symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000.

• Add if a larger symbol precedes a smaller (e.g., VI = 6).

• Subtract if a smaller precedes a larger (e.g., IV = 4).

• Repeat up to three times (e.g., III = 3).

🚀 Beyond 3999:

• No standard exists; a vinculum (overline) may denote thousands (e.g., V̅ = 5000).

🌌 Large Numbers (1 Billion):

• Non-standard; repeating M thousands of times is impractical.
