MDCCCXCIX Roman Numerals
MDCCCXCIX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MDCCCXCIX = M + DCCC + XC + IX = 1000 + 800 + 90 + 9 = 1899. The higher roman numerals precede the lower numerals resulting in the correct translation of MDCCCXCIX Roman Numerals. In this article, we will explain how to convert MDCCCXCIX Roman numerals in the correct number translation.
 MDCCCXCIX = M + D + C + C + (C  X) + (X  I)
 MDCCCXCIX = 1000 + 500 + 100 + 100 + (100  10) + (10  1)
 MDCCCXCIX = 1899
How to Write MDCCCXCIX Roman Numerals?
The numerical value of MDCCCXCIX 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.
 MDCCCXCIX = M + D + C + C + (C  X) + (X  I) = 1000 + 500 + 100 + 100 + (100  10) + (10  1) = 1899
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MDCCCXCIX = M + DCCC + XC + IX = 1000 + 800 + 90 + 9 = 1899

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MI, M > I, so MI = M + I = 1000 + 1 = 1001
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CM, C < M, so CM = M  C = 1000  100 = 900
 When a letter is repeated 2 or 3 times, they get added. For example: XXX = X + X + X = 10 + 10 + 10 = 30
 The same letter cannot be used more than three times in succession.

MDCCCXCIX Roman Numerals Examples

Example 2: Find the Sum of MDCCCXXXIV and MDCCCXCIX Roman Numerals.
Solution:
MDCCCXXXIV = 1000 + 800 + 30 + 4 = 1834 and MDCCCXCIX = 1000 + 800 + 90 + 9 = 1899
Now, MDCCCXXXIV + MDCCCXCIX = 1834 + 1899 = 3733
Since, MMMDCCXXXIII = 3000 + 700 + 30 + 3 = 3733
Therefore, the sum of MDCCCXXXIV and MDCCCXCIX roman numerals is MMMDCCXXXIII 
Example 3: Evaluate the following expression: MDCCCXCIX  LX + XVIII.
Solution:
MDCCCXCIX = 1899, LX = 60, and XVIII = 18
⇒ MDCCCXCIX  LX + XVIII = 1899  60 + 18 = 1857
⇒ The difference is 1857, which can be written as MDCCCLVII. 
Example 4: Find the Difference Between MDCCCXCIX and CCXII.
Solution:
Roman Numeral MDCCCXCIX is equal to 1899 and CCXII is 212.
Now, MDCCCXCIX  CCXII = 1899  212 = 1687
Since, 1687 = MDCLXXXVII
Therefore, MDCCCXCIX  CCXII = MDCLXXXVII
