Roman Numerals — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A monument shows MDCCLXXVI as its founding year. Which year is that?
A) 1776
B) 1676
C) 1876
D) 1976
Adding 1000, 700, 70, and 6 gives 1776, the year the United States declared independence.
2. Which Roman numeral equals 2500?
A) MMC
B) MMD
C) MD
D) MMM
MMD equals 1000 plus 1000 plus 500, totaling exactly 2500 in standard Roman form.
3. Some clock faces show IIII for 4 instead of IV. Which form is the modern standard?
A) IIII
B) IIIV
C) IV
D) VI
Modern standard writing uses IV for four because subtractive notation keeps numerals short and consistent.
4. Which Roman numeral represents the year 2100?
A) MMI
B) MMX
C) MMD
D) MMC
MMC equals 2000 plus 100, which is 2100, the final year of the 21st century by standard counting.
Part B: Fill in the Blank
Write the correct answer on each line.
1. Convert 2024 to Roman numerals: MMXXIV.
MM is 2000, XX is 20, and IV is 4, so 2024 is MMXXIV in Roman form.
2. Convert 1500 to Roman numerals: MD.
M equals 1000 and D equals 500, so 1500 is written MD in Roman form.
3. Convert 2999 to Roman numerals: MMCMXCIX.
Two M's give 2000, CM is 900, XC is 90, and IX is 9, totaling 2999.
4. If a building was built in MDCCC, what century was that? 19th century.
1800 falls inside the 19th century, which covers years 1801 through 1900 by standard counting.
5. Some old clocks show IIII for the 4 position. The modern standard form is IV.
IV uses subtractive notation, the modern accepted form, even though IIII appears on many traditional clocks.
