I, it represents -1; it can be repeated a maximum of thrice, i.e., III.
• The symbol's value gets added to itself the times' the symbol has been repeated. For example, 300 - CCC, 200 - CC
• Some symbols in the Roman Number system are never repeated, and the symbols are D, L, and V.
• There are symbols in the number system that are never used for subtraction purposes and are written before the greater value symbol.
• The symbol I can subtract from only V and X, respectively, and the X can subtract from L, M, and C only.
• When the symbol of lesser value comes before the greater value symbol, it will be subtracted. For example
IX = X - I = 9

1 - I

5 - V

10 - X

50 - L

100 - C

500 - D

### Conversion of Roman Numerals to Numbers

Rule 1: If one or more symbols are placed after another letter of greater value than add the amount,

• VIII = 8 (V + III)
• LXX = 70 (50 + 10 + 10)
• MCC = 1200 (1000 + 100 +100)

Rule 2: If a symbol is placed before another letter of greater value, subtract the amount

IX = 9 (10 - 1= 9)

CCM = 800 (1000- 100 - 100 = 800)

### Solved Examples

Question: Write 78 in Roman Numeral form

Solution: 78 = 70 + 8

= (50 + 20) (10 - 2)

= LXX + VIII

= LXXVIII

Hence, 78 = LXXVIII

Question: Write 3575 in the Roman Numeral form

Answer: It is a four-digit number that breaks down into 3000, 500, 70, and 5.

3575= 3000 + 500 + 70 + 5

So

5 = V

70 = LXX

500 = D

3000 = MMM

3575 = MMM+ D+ LXX +V

= MMMDLXXV

Question: Determine Answer of the Following Questions

1) LXXX

Ans: = 50 + 30

= 80

2) C + LX

Ans: = 100 + 60

= 160

3) MXXII - LXXX- LII

Ans: MXXII

= M + XX +II

= 1000 + 20 + 2

= 1022

LXX

= L +XXX

= 50 + 30

= 80

LII

= L + II

= 50 + 2

= 52

= 1022- 80-52

= 1022-132

= 890

4) MMM+ LLL +XX

Ans: MMM

= 1000 + 1000 + 1000

= 3000

LLL

= 50 + 50 + 50

= 150

XX

= 10 + 10

= 20

= 3000 + 150 + 20

= 3170
