Answer 6

The trick is to take the binary and change it to decimal, work it out and then take it as a form of binary again.

1010 -> 10
1001 -> 9
10 + 9 = 19

      128    64    32    16    8    4    2    1 19 =     0       0      0      1      0    0   1     1

Ans = 0001 0011

Question 7

Add 10 0110 and 11 0101

Answer 7

32 16 8 4 2 1
1 0 0 1 1 0 -> 38

38 + 53 = 91

128 64 32 16 8 4 2 1
0 1 0 1 1 0 1 1

Ans = 0101 1011

Question 8

Add 10 1101 and 11 1101

Answer 8

32 16 8 4 2 1
1 0 1 1 0 1 -> 45
