Roman Numerals 1 to 20 Examples

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 
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. 
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 
Example 4: Find all Perfect Cubes between Roman Numerals from 1 to 20.
Solution:
The list of all perfect cubes from 1 to 20 are: 1, 8. Therefore, all perfect cubes between roman numerals 1 to 20 are I, VIII.
