What Do Roman Numerals Questions Look Like?
Roman numeral questions test your ability to convert Roman symbols into ordinary numbers, perform calculations, and express the final result back in standard Roman notation. Here is a worked example.
Convert Before Multiplying
Question: Work out XI multiplied by IV.
Options: A XXIII, B XLIV, C VIII, D LXIX, E LXXVIII
Method:
XI = 11 and IV = 4.
11 × 4 = 44.
44 = 40 + 4 = XL + IV = XLIV.
Answer: B
Tip: Treat IV as 4, not 6. The smaller I before V means subtract.
Rules to Help You Solve Roman Numerals Questions
To solve Roman numeral questions like the example above, convert to digits before calculating. Follow these four rules:
Rule 1: Know the core symbols
Roman numerals are built from symbol values: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, and M = 1000.
Example: LXVI = 50 + 10 + 5 + 1 = 66.
Rule 2: Watch subtractive pairs
Standard Roman notation uses six subtractive pairs: IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, and CM = 900. In each pair, subtract the smaller symbol from the larger one.
Example: 49 = 40 + 9 = XLIX. IL is not a valid subtractive pair.
Rule 3: Calculate in normal numbers
Convert each Roman numeral first, then use the operation shown in the question.
Example: XI multiplied by IV is 11 × 4 = 44.
Rule 4: Convert the answer carefully
Break the result into thousands, hundreds, tens, and ones, using subtractive forms where needed.
In the standard notation used here, I, X, C, and M can repeat up to three times consecutively. V, L, and D are not repeated. Write 40 as XL, not XXXX.
Example: 93 = 90 + 3 = XCIII.
Two More Worked Examples
Here are two more examples showing multi-step calculations and missing-value equations.
Complete a Multi-Step Calculation
Question: Multiply V by XI, then add XXXVIII.
Options: A XCIII, B CXXV, C CIX, D LV, E CXXXIV
Method:
V = 5, XI = 11, and XXXVIII = 38.
5 × 11 + 38 = 55 + 38 = 93.
93 = 90 + 3 = XC + III = XCIII.
Answer: A
Tip: Complete the arithmetic before converting back. Do not try to multiply the Roman symbols directly.
Find a Missing Value
Question: What Roman numeral should replace the question mark in MDCLXIII − ? = MXCIII?
Options: A CCCV, B DXX, C DLXX, D DCCXCIII, E CDXXIII
Method:
MDCLXIII = 1000 + 500 + 100 + 50 + 10 + 3 = 1663.
MXCIII = 1000 + 90 + 3 = 1093. The XC pair represents 100 − 10 = 90.
1663 - ? = 1093, so ? = 1663 - 1093 = 570.
570 = 500 + 50 + 20 = D + L + XX = DLXX.
Check by substituting the answer: 1663 − 570 = 1093, so DLXX satisfies the equation.
Answer: C
Tip: In missing-value questions, isolate the question mark first, then convert that value into Roman numerals.
