Roman Numerals 1 to 20 Examples

  1. Example 1: Using your knowledge of Roman numerals 1 to 20, Find the value of XVI - V.

    Solution:

    XVI = 10 + 6 = 16 and V = 5. Therefore, XVI - V = 16 - 5 = 11.
    Now, XI = 10 + 1 = 11

  2. Example 2: Using Roman numerals 1 to 20 chart, find the product of III and IV.

    Solution:

    III = 3 and IV = 4
    Now, III × IV = 3 × 4 = 12
    Since, 12 = 10 + 1 + 1 = X + I + I = XII
    Therefore, the product of III and IV is XII.

  3. Example 3: Find the Value of XII + (XI - XIV) + VIII.

    Solution:

    Using Roman numerals 1 to 20 chart: XII = 10 + 2 = 12, XI = 10 + 1 = 11, XIV = 10 + 4 = 14, VIII = 8.
    Therefore, XII + (XI - XIV) + VIII = 12 + (11 - 14) + 8 = 17
    Now, 17 = 10 + 5 + 1 + 1 = X + V + I + I = XVII

  4. Example 4: Find all Perfect Cubes between Roman Numerals from 1 to 20.
