MCMXLII Roman Numerals
MCMXLII Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MCMXLII = M + (M  C) + (L  X) + I + I = 1000 + (1000  100) + (50  10) + 1 + 1 = 1942. The higher roman numerals precede the lower numerals resulting in the correct translation of MCMXLII Roman Numerals. In this article, we will explain how to convert MCMXLII Roman numerals in the correct number translation.
 MCMXLII = M + CM + XL + II
 MCMXLII = 1000 + 900 + 40 + 2
 MCMXLII = 1942
How to Write MCMXLII Roman Numerals?
The numerical value of MCMXLII Roman Numerals can be obtained by using any of the two methods given below:
Method 1: In this method, we break the roman numerals into single letters, write the numerical value of each letter and add/subtract them.
 MCMXLII = M + (M  C) + (L  X) + I + I = 1000 + (1000  100) + (50  10) + 1 + 1 = 1942
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MCMXLII = M + CM + XL + II = 1000 + 900 + 40 + 2 = 1942

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: DI, D > I, so DI = D + I = 500 + 1 = 501
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XC, X < C, so XC = C  X = 100  10 = 90
 When a letter is repeated 2 or 3 times, they get added. For example: MM = M + M = 1000 + 1000 = 2000
 The same letter cannot be used more than three times in succession.

MCMXLII Roman Numerals Examples

Example 1: Find the Difference Between MCMXLII and MDCCCXXII.
Solution:
Roman Numeral MCMXLII is equal to 1942 and MDCCCXXII is 1822.
Now, MCMXLII  MDCCCXXII = 1942  1822 = 120
Since, 120 = CXX
Therefore, MCMXLII  MDCCCXXII = CXX 
Example 2: Evaluate the following expression: MCMXLII  LXXXV + XV.
Solution:
MCMXLII = 1942, LXXXV = 85, and XV = 15
⇒ MCMXLII  LXXXV + XV = 1942  85 + 15 = 1872
⇒ The difference is 1872, which can be written as MDCCCLXXII. 
Example 4: Find the Sum of MDCCXCIX and MCMXLII Roman Numerals.
Solution:
MDCCXCIX = 1000 + 700 + 90 + 9 = 1799 and MCMXLII = 1000 + 900 + 40 + 2 = 1942
Now, MDCCXCIX + MCMXLII = 1799 + 1942 = 3741
Since, MMMDCCXLI = 3000 + 700 + 40 + 1 = 3741
Therefore, the sum of MDCCXCIX and MCMXLII roman numerals is MMMDCCXLI
