No problem, let's work through this together. We're starting with 39930 and are subtracting 38722 from it.

Step 1: We'll start by subtracting the digit 2 and the borrow 0 from 0 in column 1 and get -2.
We add -2 to 10 and get 8 as the first digit of the result.

Step 2: We'll start by subtracting the digit 2 and the borrow 1 from 3 in column 2 and get 0.
0 is the next digit of our result.

Step 3: We'll start by subtracting the digit 7 and the borrow 0 from 9 in column 3 and get 2.
2 is the next digit of our result.

Step 4: We'll start by subtracting the digit 8 and the borrow 0 from 9 in column 4 and get 1.
1 is the next digit of our result.

Step 5: We'll start by subtracting the digit 3 and the borrow 0 from 3 in column 5 and get 0.
0 is the next digit of our result.

So, 39930 - 38722 = 1208.
