Basic Rules for Writing Roman Numerals

• Roman numerals use seven symbols: I, V, X, L, C, D, and M.

• If a smaller numeral comes after a larger one, values are added (VI = 6).

• If a smaller numeral comes before a larger one, it is subtracted (IV = 4).

• I, X, C, and M can be repeated up to three times; V, L, and D are not repeated.

• Roman numerals are generally written from left to right in decreasing value.
  
  

Solved Examples on DLX Roman Numerals

Example 1: Find the value of DLX Roman numerals in numbers.

Solution:

• D = 500, L = 50, X = 10 

• Add them: 500 + 50 + 10 = 560.

DLX in Roman numerals is equivalent to 560.

Example 2: Write 560 in Roman numerals.

Solution:

• Break down 560 into 500 + 50 + 10

• D = 500, L = 50 , X = 10

• Combining the symbols we get 500 + 50 + 10 = D + L + X  = DLX

DLX in Roman numerals is 560.

Example 3: Identify Roman numerals before and after DLX.

Solution: DLX Roman Numerals is equal to 560

• Before: DLIX = 559

• After: DLXI = 561

Example 4: DLX × IV = ?

Solution: Multiplying DLX (560) by IV (4) gives 2240
2240 in Roman numerals is MMCCXL.
i.e., DLX × IV = MMCCXL

Example 5: Subtract LX from DLX. (DLX − LX)

Solution: Convert first:

• DLX = 560

• LX = 50 + 10 = 60

Now subtract:

560 - 60 = 500

Convert back to Roman numerals:

500 = D

DLX - LX = D
