  10101
-  1011
--------

1. Start from the rightmost digit and subtract the corresponding digits. If the minuend digit is smaller than the subtrahend digit, borrow 1 from the next higher significant digit.

2. Continue this process for all digits, moving from right to left.

Let's go step by step:

Step 1: Subtract the rightmost digits (1 - 1):

  10101
-  1011
--------
       0

Step 2: Subtract the next digits (0 - 1). Since 0 is smaller than 1, we need to borrow 1 from the next higher digit (2nd digit from the right, which is 0).

      10

Step 3: Now subtract the borrowed 1 from the next higher digit (2nd digit from the left):

     110

Step 4: Subtract the next digits (0 - 0):

    1100

Step 5: Subtract the next digits (1 - 1):

  10101
-  1011
--------
   01100

Step 6: Subtract the leftmost digits (1 - 0):

  10101
-  1011
--------
  001100

The result of subtracting 10101 from 1011 in binary is 1100. In decimal notation, this is equal to 12. So:

10101 (binary) - 1011 (binary) = 1100 (binary) = 12 (decimal)
