Question

When we perform subtraction on -7 and 1 the answer in 2's complement form is ________?

Answer 1

Answer:

0110 is the complement formed

Answer 2

To Find,

Subtraction of -7 and 1

Solution:

-7 - 1

7 = 0111

1's complement = 1000

2's complement = 1000 + 1 = 1001

1 = 0001

1's complement = 1110

2's complement = 1110 + 1 = 1111

1 0 0 1

+  1  1  1  1

1 1 0 0 0

We get the end-around carry number one. This carry will be discarded.

And we have 1000.

Obtain the 2's complement of 1000 now.

1's complement = 0111

2's complement = 0111 + 1 = 1000

So, the final answer is 1000

When we perform subtraction on -7 and 1 the answer in 2’s complement form is 1000.
