  • According to the place value write down the individual value of roman numeral and add all of them to know the value of each number given to you.
  • After finding the Arabic numbers add them to get the resultant value.
  • Later convert the resultant value to Roman Numeral.


Add LXX and VII?


Given Input roman numerals are LXX and VII

Finding the Arabic numbers individually we get LXX = 50+10+10 = 70

VII = 5+1+1 =7

= 70+7

= 77



  • Find the individual values of the Roman Numerals given to you at first.
  • Later, subtract the numeric values.
  • Finally, convert the result obtained to roman numeral value.


Subtract LI from XC?


Given Roman Numerals are LI and XC

LI = 50+1 = 51

XC= 100-10 = 90

Subtracting the numeric values we get

= 90- 51

= 39

  • Convert the result obtained to Roman Numeral back.


Find the Product of Roman Numerals IX and XC?


Given Roman Numerals are IX and XC

Converting them to Individual Arabic Number Values we get

IX = 9

XC = 100-10 = 90

Multiply the Individual Arabic Number Values obtained

= 9*90

= 810

Changing the result to Roman Numeral we get the result as DCCCX
