Roman Numeral Rules
Seven symbols are used: I(1), V(5), X(10), L(50), C(100), D(500), M(1000). Symbols are written largest to smallest left to right. A smaller symbol before a larger one means subtraction — IV=4, IX=9, XL=40, XC=90, CD=400, CM=900.

MMXXIV = 2024. MM=2000, XX=20, IV=4. So MMXXIV = 2000+20+4 = 2024. Our converter handles all numbers from 1 to 3,999.
