MCMXLV Roman Numerals
MCMXLV Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MCMXLV = M + (M  C) + (L  X) + V = 1000 + (1000  100) + (50  10) + 5 = 1945. The higher roman numerals precede the lower numerals resulting in the correct translation of MCMXLV Roman Numerals. In this article, we will explain how to convert MCMXLV Roman numerals in the correct number translation.
 MCMXLV = M + CM + XL + V
 MCMXLV = 1000 + 900 + 40 + 5
 MCMXLV = 1945
How to Write MCMXLV Roman Numerals?
The numerical value of MCMXLV 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.
 MCMXLV = M + (M  C) + (L  X) + V = 1000 + (1000  100) + (50  10) + 5 = 1945
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MCMXLV = M + CM + XL + V = 1000 + 900 + 40 + 5 = 1945
Therefore, the numerical value of MCMXLV roman numerals is 1945.

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: IV, I < V, so IV = V  I = 5  1 = 4
 When a letter is repeated 2 or 3 times, they get added. For example: CCC = C + C + C = 100 + 100 + 100 = 300
 The same letter cannot be used more than three times in succession.

 MCMXLI = 1000 + 900 + 40 + 1 = 1941
 MCMXLII = 1000 + 900 + 40 + 2 = 1942
 MCMXLIII = 1000 + 900 + 40 + 3 = 1943
 MCMXLIV = 1000 + 900 + 40 + 4 = 1944
 MCMXLV = 1000 + 900 + 40 + 5 = 1945
 MCMXLVI = 1000 + 900 + 40 + 6 = 1946
 MCMXLVII = 1000 + 900 + 40 + 7 = 1947
 MCMXLVIII = 1000 + 900 + 40 + 8 = 1948
 MCMXLIX = 1000 + 900 + 40 + 9 = 1949
MCMXLV Roman Numerals Examples

Example 2: Find the Sum of CDXXX and MCMXLV Roman Numerals.
Solution:
CDXXX = 400 + 30 = 430 and MCMXLV = 1000 + 900 + 40 + 5 = 1945
Now, CDXXX + MCMXLV = 430 + 1945 = 2375
Since, MMCCCLXXV = 2000 + 300 + 70 + 5 = 2375
Therefore, the sum of CDXXX and MCMXLV roman numerals is MMCCCLXXV 
Example 3: Find the Difference Between MCMXLV and CCCXCVII.
Solution:
Roman Numeral MCMXLV is equal to 1945 and CCCXCVII is 397.
Now, MCMXLV  CCCXCVII = 1945  397 = 1548
Since, 1548 = MDXLVIII
Therefore, MCMXLV  CCCXCVII = MDXLVIII 
Example 4: Evaluate the following expression: MCMXLV  LXX + XIII.
Solution:
MCMXLV = 1945, LXX = 70, and XIII = 13
⇒ MCMXLV  LXX + XIII = 1945  70 + 13 = 1888
⇒ The difference is 1888, which can be written as MDCCCLXXXVIII.
