Decimal number weights
100 = 1 → first digit, weights one
101 = 10 → second digit, weights ten
102 = 100 → third digit, weights hundred
103 = 1000 → fourth digit, weights thousand
104 = 1000 → fifth digit, weights ten thousand
etc.
Example 1:
Describe a decimal number 2015 in the system numbers
Completion:
2015 (10) =
5 → 5 × 100 = 5
1 → 1 × 101 = 10
0 → 0 × 102 = 0
2 → 2 × 103 = 2000
2015 → 5 + 10 + 0 + 2000 = 2015
Example 2:
Describe a decimal number 1000518 in the system numbers
Completion:
1000518 (10) =
8 → 8 × 100 = 8
1 → 1 × 101 = 10
5 → 5 × 102 = 500
0 → 0 × 103 = 0
0 → 0 × 104 = 0
0 → 0 × 105 = 0
1 → 1 × 106 = 1000000
1000518 → 8 + 10 + 500 + 0 + 0 + 0 + 1000000 = 1000518.
