What is the result of subtracting the binary number 101 from 1101?

Step 1: Align the numbers

1101

• 101

Step 2: Perform the subtraction from right to left.

1st column: 1 - 1 = 0

2nd column: 0 - 0 = 0

3rd column: You can't subtract 1 from 0, so you need to borrow 1 from the next column. After borrowing, the 0 becomes 10 in binary, so 10 - 1 = 1.

4th column: After borrowing, 1 becomes 0, so 0 - 1 is not possible. But since there's no other column to borrow from, the result in this column is 0.

So, the result of the subtraction is 1000.
