What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: DC, D > C, so DC = D + C = 500 + 100 = 600
 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.

XLV Roman Numerals Examples

Example 1: Find the Sum of MLXXV and XLV Roman Numerals.
Solution:
MLXXV = 1000 + 70 + 5 = 1075 and XLV = 40 + 5 = 45
Now, MLXXV + XLV = 1075 + 45 = 1120
Since, MCXX = 1000 + 100 + 20 = 1120
Therefore, the sum of MLXXV and XLV roman numerals is MCXX 
Example 3: Find the Difference Between XLV and II.
Solution:
Roman Numeral XLV is equal to 45 and II is 2.
Now, XLV  II = 45  2 = 43
Since, 43 = XLIII
Therefore, XLV  II = XLIII 
Example 4: Find the Product of Roman Numerals XLV and LXXV.
Solution:
XLV = 40 + 5 = 45 and LXXV = 70 + 5 = 75
Now, XLV × LXXV = 45 × 75 = 3375
Since, MMMCCCLXXV = 3000 + 300 + 70 + 5 = 3375
Therefore, XLV × LXXV = MMMCCCLXXV
