1. Find subtraction of (111)2 and (101)2
Solution:
Solution is
Step by step solution :
Step by step solution :Step-1 : 1 - 1
Here 1
= 1, so directly subtract it
=1-1=02Step-2 : 1 - 0
Here 1
> 0, so directly subtract it
=1-0=12Step-3 : 1 - 1
Here 1
= 1, so directly subtract it
=1-1=02
2. Find subtraction of (1100)2 and (1001)2
Solution:
Solution is
Step by step solution :
Step by step solution :Step-1 : 0 - 1
Here 0
< 1, we take borrow from 0, which takes borrow from 1
So 1 becomes 0, 0 becomes 1 and 0 becomes 0+2=2
=2-1=12Step-2 : 1 - 0
Here 1
> 0, so directly subtract it
=1-0=12Step-3 : 0 - 0
Here 0
= 0, so directly subtract it
=0-0=02Step-4 : 1 - 1
Here 1
= 1, so directly subtract it
=1-1=02
3. Find subtraction of (11011)2 and (1101)2
Solution:
Solution is
Step by step solution :
Step by step solution :Step-1 : 1 - 1
Here 1
= 1, so directly subtract it
=1-1=02Step-2 : 1 - 0
Here 1
> 0, so directly subtract it
=1-0=12Step-3 : 0 - 1
Here 0
< 1, we take borrow from 1
So 1 becomes 0 and 0 becomes 0+2=2
=2-1=12Step-4 : 0 - 1
Here 0
< 1, we take borrow from 1
So 1 becomes 0 and 0 becomes 0+2=2
=2-1=12Step-5 : 0 - 0
Here 0
= 0, so directly subtract it
=0-0=02
