Basic Rules to Interpret 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: XL, X < L, so XL = L  X = 50  10 = 40.
 When a letter is repeated multiple times, they get added. For example: MM = M + M = 1000 + 1000 = 2000
 The same letter cannot be used more than three times in succession.

Example 2: Find the value of 31  1. Write the result in form of roman numerals.
Solution:
Solving the given problem, 31  1 = 30
To determine the value of 31  1 in roman numerals, we will express 31 first, in the expanded form, i.e. 31 = 30 + 1 = X + X + X + I = XXXI
31  1 = XXXI  I = XXX = 30 
Example 3: Find the Difference Between 63 and 1 in Roman Numerals.
Solution:
Solving the given problem, 63  1 = 62
To determine the value of 63  1 = 62 in roman numerals, we will express 62 in the expanded form, i.e., 62 = 60 + 2 = L + X + II = LXII 
Example 4: Find the Value of (24  20) + 1 in roman numerals.
Solution:
Solving (24  20) + 1 = 4 + 1 = 5. Now, we will write the answer, that is, 5 = V.
