Unlike the Hindu-Arabic Numeral System, Roman Numeral System uses 7 basic symbols to represent different numbers. The symbols are as follows :

I = 1 V =5 X= 10

L = 50 C =100 D=500

M= 1000

1) If symbol is repeated then its value is added.

2)The symbols I,X,C and M can be repeated maximum 3 times.

3)The symbols V,L and D can never be repeated.

4)If a symbol with smaller value is written on right of greater value then smaller value is added to the greater one.

5)If a symbol with smaller value is written on left of greater value then smaller value is subtracted from the greater one.

b)395 ---> CCCXCV

c) 62 ---> LXII

b)DCC ----> 700

XXII = 22

CD = 400

XXII + CD = 22 +400

= 422

XLIV = 44

LIV = 54

∴ XLIV + LIV = 44 + 54

= 98

98 = XCVIII

DCC = 700

LXXXV = 85

∴DCC - LXXXV = 700 - 84

= 616

616 = DCXVI
