Best Answer

Binary sum 1001+101+11 = 10001

Recall:

0 + 0 = 0

0 + 1 = 0

1 + 0 = 0

1 + 1 = 10

Start from the end:

1 + 1 + 1 = 1 carry on 1

1 + 1 + 0 + 0 = 0 carry on 1

1 + 1 + 0 = 0 carry on 1

1 + 1 = 10

or

1001 = 23 + 20 = 8 + 1 = 9

101 = 22 + 20 = 4 + 1 = 5

11 = 21 + 20 = 2 + 1 = 3

17 = 24 + 20 = 10001
