XLII Roman Numerals
XLII Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. XLII = (L  X) + I + I = (50  10) + 1 + 1 = 42. The higher roman numerals precede the lower numerals resulting in the correct translation of XLII Roman Numerals. In this article, we will explain how to convert XLII Roman numerals in the correct number translation.
 XLII = XL + II
 XLII = 40 + 2
 XLII = 42
How to Write XLII Roman Numerals?
The numerical value of XLII 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.
 XLII = (L  X) + I + I = (50  10) + 1 + 1 = 42
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
 XLII = XL + II = 40 + 2 = 42
Therefore, the numerical value of XLII roman numerals is 42.

What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: CX, C > X, so CX = C + X = 100 + 10 = 110
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CD, C < D, so CD = D  C = 500  100 = 400
 When a letter is repeated 2 or 3 times, they get added. For example: XX = X + X = 10 + 10 = 20
 The same letter cannot be used more than three times in succession.

XLII Roman Numerals Examples

Example 2: Find the Sum of CMXXI and XLII Roman Numerals.
Solution:
CMXXI = 900 + 20 + 1 = 921 and XLII = 40 + 2 = 42
Now, CMXXI + XLII = 921 + 42 = 963
Since, CMLXIII = 900 + 60 + 3 = 963
Therefore, the sum of CMXXI and XLII roman numerals is CMLXIII 
Example 3: Find the Product of Roman Numerals XLII and LXXXV.
Solution:
XLII = 40 + 2 = 42 and LXXXV = 80 + 5 = 85
Now, XLII × LXXXV = 42 × 85 = 3570
Since, MMMDLXX = 3000 + 500 + 70 = 3570
Therefore, XLII × LXXXV = MMMDLXX 
Example 4: Find the Difference Between XLII and XXXVI.
Solution:
Roman Numeral XLII is equal to 42 and XXXVI is 36.
Now, XLII  XXXVI = 42  36 = 6
Since, 6 = VI
Therefore, XLII  XXXVI = VI
