XL Roman Numerals Examples

Example 1: Find the Sum of MMCMLI and XL Roman Numerals.
Solution:
MMCMLI = 2000 + 900 + 50 + 1 = 2951 and XL = 40
Now, MMCMLI + XL = 2951 + 40 = 2991
Since, MMCMXCI = 2000 + 900 + 90 + 1 = 2991
Therefore, the sum of MMCMLI and XL roman numerals is MMCMXCI 
Example 2: Find the Difference Between XL and VIII.
Solution:
Roman Numeral XL is equal to 40 and VIII is 8.
Now, XL  VIII = 40  8 = 32
Since, 32 = XXXII
Therefore, XL  VIII = XXXII 
Example 4: Find the Product of Roman Numerals XL and LXXXVIII.
Solution:
XL = 40 and LXXXVIII = 80 + 8 = 88
Now, XL × LXXXVIII = 40 × 88 = 3520
Since, MMMDXX = 3000 + 500 + 20 = 3520
Therefore, XL × LXXXVIII = MMMDXX
