The higher roman numerals precede the lower numerals resulting in the correct translation of MDCCXLIII Roman Numerals. In this article, we will explain how to convert MDCCXLIII Roman numerals in the correct number translation.
 MDCCXLIII = M + D + C + C + (L  X) + I + I + I
 MDCCXLIII = 1000 + 500 + 100 + 100 + (50  10) + 1 + 1 + 1
 MDCCXLIII = 1743
How to Write MDCCXLIII Roman Numerals?
The numerical value of MDCCXLIII 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.
 MDCCXLIII = M + D + C + C + (L  X) + I + I + I = 1000 + 500 + 100 + 100 + (50  10) + 1 + 1 + 1 = 1743
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 MDCCXLIII = M + DCC + XL + III = 1000 + 700 + 40 + 3 = 1743
Therefore, the numerical value of MDCCXLIII roman numerals is 1743.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: MX, M > X, so MX = M + X = 1000 + 10 = 1010
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XC, X < C, so XC = C  X = 100  10 = 90
 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.

MDCCXLIII Roman Numerals Examples

Example 1: Find the Difference Between MDCCXLIII and MCXXIV.
Solution:
Roman Numeral MDCCXLIII is equal to 1743 and MCXXIV is 1124.
Now, MDCCXLIII  MCXXIV = 1743  1124 = 619
Since, 619 = DCXIX
Therefore, MDCCXLIII  MCXXIV = DCXIX 
Example 2: Evaluate the following expression: MDCCXLIII  LXXVII + II.
Solution:
MDCCXLIII = 1743, LXXVII = 77, and II = 2
⇒ MDCCXLIII  LXXVII + II = 1743  77 + 2 = 1668
⇒ The difference is 1668, which can be written as MDCLXVIII. 
Example 3: Find the Sum of MLVIII and MDCCXLIII Roman Numerals.
Solution:
MLVIII = 1000 + 50 + 8 = 1058 and MDCCXLIII = 1000 + 700 + 40 + 3 = 1743
Now, MLVIII + MDCCXLIII = 1058 + 1743 = 2801
