Explanation:

The given answers are in Binary.

In binary we add the digits in 1 and 0 form.

Addition in Binary:

1 + 0 = 1

0 + 1 = 1

0 + 0 = 0

1 + 1 = 10

Subtraction in Binary:

1 - 0 = 1

1 - 1 = 0

0 - 1 = 1 (it's because the 0 borrows a 1)

0 - 0 = 0

        Answer:   01 1 1 0 1 0 1

Explanation:

In Binary addition when you add 1 + 1 = 0, carry over the 1, i.e 10

in Subtraction when you subtract 0-1 = 1,  brow 1 from left side, resulting in -1 carried over.
