Explicație pas cu pas:

23 : 2 = 11 rest 1

11 : 2 = 5 rest 1

5 : 2 = 2 rest 1

2 : 2 = 1 rest 0

1 : 2 = 0 rest 1

10111

__________

69 : 2 = 34 rest 1

34 : 2 = 17 rest 0

17 : 2 = 8 rest 1

8 : 2 = 4 rest 0

4 ; 2 = 2 rest 0

2 : 2 = 1 rest 0

1 : 2 = 0 rest 1

1000101

______________

48 : 2 = 24 rest 0

24 : 2 = 12 rest 0

12 : 2 = 6 rest 0

6 : 2 = 3 rest 0

3 : 2 = 1 rest 1

1 : 2 = 0 rest 1

110000

______________

1001

1*2^3 + 0*2^2 + 0*2^1 + 1*2^0 = 8 + 1 = 9

______________

1010

1*2^3 + 0*2^2 + 1*2^1 + 0*2^0 = 8 + 2 = 10
