Number Systems‚ Base Conversions‚ and Computer Data Representation Decimal and Binary Numbers When we write decimal (base 10) numbers‚ we use a positional notation system. Each digit is multiplied by an appropriate power of 10 depending on its position in the number: For example: 843 = 8 x 102 + 4 x 101 + 3 x 100 = 8 x 100 + 4 x 10 + 3 x 1 = 800 + 40 + 3 For whole numbers‚ the rightmost digit position is the one’s position (100 = 1). The numeral in that position indicates how many ones
