Decimal Number System
The decimal number system consists of ten digits that are from 0 to 9 (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The base of the decimal number system is 10. These digits can be used to represent any numeric value. For example, the decimal number 153 consists of the digit 3 in one’s place, the digit 5 in tens place and the digit 1 in hundreds place which can be represented as,
(1 × 102) + (5 × 101) + (3 × 100 )
= (1 × 100) + (5 × 10) + (3 × 1), {As 100 = 1}
= 100 + 50 + 3
= 153
