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

Therefore, XL - VIII = XXXII
Example 3: Find the Quotient of 40 and 26.
Solution:
The roman numeral XL is 40 and XXVI is 26.
Now, when we divide XL by XXVI i.e. 40 ÷ 26, the quotient is 1.
Since, 1 = I
Therefore, XL ÷ XXVI = I
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
