CXXXIX Roman Numerals
CXXXIX Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. CXXXIX = C + X + X + X + (X  I) = 100 + 10 + 10 + 10 + (10  1) = 139. The higher roman numerals precede the lower numerals resulting in the correct translation of CXXXIX Roman Numerals. In this article, we will explain how to convert CXXXIX Roman numerals in the correct number translation.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MD, M > D, so MD = M + D = 1000 + 500 = 1500
 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: CC = C + C = 100 + 100 = 200
 The same letter cannot be used more than three times in succession.

CXXXIX Roman Numerals Examples

Example 2: Find the Sum of CCCXX and CXXXIX Roman Numerals.
Solution:
CCCXX = 300 + 20 = 320 and CXXXIX = 100 + 30 + 9 = 139
Now, CCCXX + CXXXIX = 320 + 139 = 459
Since, CDLIX = 400 + 50 + 9 = 459
Therefore, the sum of CCCXX and CXXXIX roman numerals is CDLIX 
Example 3: Find the Product of Roman Numerals CXXXIX and XXIII.
Solution:
CXXXIX = 100 + 30 + 9 = 139 and XXIII = 20 + 3 = 23
Now, CXXXIX × XXIII = 139 × 23 = 3197
Since, MMMCXCVII = 3000 + 100 + 90 + 7 = 3197
Therefore, CXXXIX × XXIII = MMMCXCVII 
Example 4: Find the Difference Between CXXXIX and CXVI.
Solution:
Roman Numeral CXXXIX is equal to 139 and CXVI is 116.
Now, CXXXIX  CXVI = 139  116 = 23
Since, 23 = XXIII
Therefore, CXXXIX  CXVI = XXIII
