Frequently Asked Questions: 1 to 100
How do you write 1 to 100 in Roman numerals?
To write 1 to 100 in Roman numerals, combine the fundamental symbols I (1), V (5), X (10), L (50), and C (100) using additive and subtractive rules. For example, 1 is I, 10 is X, 49 is XLIX, 50 is L, 99 is XCIX, and 100 is C.
Why is 49 written as XLIX instead of IL?
Roman numerals follow strict decimal place-value rules. The symbol I can only precede V and X. It cannot be subtracted from L (50) or C (100). Therefore, 49 is composed of 40 (XL) + 9 (IX) = XLIX.
Why is 99 written as XCIX instead of IC?
Under classical subtractive grammar, I can only subtract from V and X. To represent 99, you must separate 90 and 9: 90 is XC (100 - 10) and 9 is IX (10 - 1), resulting in XCIX.
What is 50 in Roman numerals?
50 is represented by the single Latin symbol L.
