### Roman Number System

#### Base Numerals

They include

• I (for representing one)
• V (for 5)
• X (for 10)
• L (for 50)
• C (for 100)
• M (for 1000)

#### Rules

• If a lesser weighted symbol appears to the left of a larger weighted symbol, the lower value is subtracted from the higher value. Examples : IV (5 -1 = 4), XC (100 – 10 = 90)
• If a lesser weighted symbol appears to the right of a larger weighted symbol, the lower value to added to the higher value. Examples : VII (5 + 1 + 1 = 7), CXX (100 + 10 + 10 = 120)

#### Deficiencies

• It is difficult to perform arithmetic operations
• It is not easy to read large Roman numbers. Movie companies supposedly use Roman numbers in their copyright dates so that the audience could not quickly figure out if a movie is too old.

### Hindu-Arabic System

#### Digits

There are ten digits 1, 2, 3, 4, 5, 6, 7, 8, 9 and most importantly 0.

#### Positional System

“The Dawn of Nothing” mphasizes the introduction of Zero thereby allowing the positional system of representing numbers.

#### Advantages

It has many advantages over the Roman Number System.

• Compact representation
• Ease of performing arithmetic operations.
