Solution

Base 2 we have to do addition and subtraction

First add the first two items

11001

11110

--------- Unit digit is 1, 10 place 1, 100 place 1. 1000 place we get 2, so make it 10 and carry over 1.

          10000 place becomes 3 so write as 11

Hence answer is

110111

Now subtract 111 from this

110111-111

= 110000

Hence final answer is 110000
