We add -3 to 10 and get 7 as the next digit of the result.

Step 3: We'll start by subtracting the digit 6 and the borrow 1 from 8 in column 3 and get 1.
1 is the next digit of our result.

Step 4: We'll start by subtracting the digit 6 and the borrow 0 from 2 in column 4 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

Step 5: We'll start by subtracting the digit 0 and the borrow 1 from 6 in column 5 and get 5.
5 is the next digit of our result.

Step 6: We'll start by subtracting the digit 8 and the borrow 0 from 1 in column 6 and get -7.
We add -7 to 10 and get 3 as the next digit of the result.

Step 7: We'll start by subtracting the digit 9 and the borrow 1 from 9 in column 7 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

Step 8: We'll start by subtracting the digit 5 and the borrow 1 from 9 in column 8 and get 3.
3 is the next digit of our result.
