What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CI, C > I, so CI = C + I = 100 + 1 = 101

CCIX Roman Numerals Examples

Example 2: Find the Sum of MMMDCLXXIX and CCIX Roman Numerals.
Solution:
MMMDCLXXIX = 3000 + 600 + 70 + 9 = 3679 and CCIX = 200 + 9 = 209
Now, MMMDCLXXIX + CCIX = 3679 + 209 = 3888
Since, MMMDCCCLXXXVIII = 3000 + 800 + 80 + 8 = 3888
Therefore, the sum of MMMDCLXXIX and CCIX roman numerals is MMMDCCCLXXXVIII 
Example 3: Find the Difference Between CCIX and LXXII.
Solution:
Roman Numeral CCIX is equal to 209 and LXXII is 72.
Now, CCIX  LXXII = 209  72 = 137
Since, 137 = CXXXVII
Therefore, CCIX  LXXII = CXXXVII 
Example 4: Find the Product of Roman Numerals CCIX and XV.
Solution:
CCIX = 200 + 9 = 209 and XV = 10 + 5 = 15
Now, CCIX × XV = 209 × 15 = 3135
Since, MMMCXXXV = 3000 + 100 + 30 + 5 = 3135
Therefore, CCIX × XV = MMMCXXXV
