How Roman numerals work
Seven letters carry all the values:
I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000
Symbols are written largest first and added together, so MMXXVI is 1000 + 1000 + 10 + 10 + 5 + 1 = 2026.
Subtractive pairs
To avoid four identical symbols in a row, a smaller value placed before a larger one is subtracted:
IV= 4,IX= 9XL= 40,XC= 90CD= 400,CM= 900
Only those six pairs are valid, and only one of each may appear. That is why standard Roman numerals stop at 3999 — there is no symbol for 5000 to build on.
