How to Write MDCLXV Roman Numerals?
The numerical value of MDCLXV 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.
 MDCLXV = M + D + C + L + X + V = 1000 + 500 + 100 + 50 + 10 + 5 = 1665
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,

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

MDCLXV Roman Numerals Examples

Example 1: Evaluate the following expression: MDCLXV  LXIX + XVI.
Solution:
MDCLXV = 1665, LXIX = 69, and XVI = 16
⇒ MDCLXV  LXIX + XVI = 1665  69 + 16 = 1612
⇒ The difference is 1612, which can be written as MDCXII. 
Example 2: Find the Difference Between MDCLXV and CCCXXIV.
Solution:
Roman Numeral MDCLXV is equal to 1665 and CCCXXIV is 324.
