In Roman numerals, if a lower valued letter is placed before a higher valued letter:
A. the equivalent is less than zero
B. the higher-valued letter is added to the lower-valued letter
C. the lower-valued letter is subtracted from the higher-valued letter
D. the lower-valued letter is divided by the higher-
valued letter
c
Rationale: In Roman numerals, if a lower-valued letter is placed before a higher-valued letter, the lower-valued letter is subtracted from the higher-valued letter. Examples: IX 5 1 and 10. In this case, you must subtract 10 2 1 5 9 (IX 5 9). XL 5 10 and 50. In this case, you must subtract 50 2 10 5 40 (XL 5 40). Roman numerals represent whole numbers, which are great-er than zero. Roman numeral characters are not divided to arrive at their equivalent Arabic number value.
