Okay, let's tackle this math problem. We're starting with 32735 and subtracting 28433.

Step 1: We'll start by subtracting the digit 3 and the borrow 0 from 5 in column 1 and get 2.
2 is the first digit of our result.

Step 2: We'll start by subtracting the digit 3 and the borrow 0 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 4 and the borrow 0 from 7 in column 3 and get 3.
3 is the next digit of our result.

Step 4: We'll start by subtracting the digit 8 and the borrow 0 from 2 in column 4 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

Step 5: We'll start by subtracting the digit 2 and the borrow 1 from 3 in column 5 and get 0.
0 is the next digit of our result.

So, 32735 - 28433 = 4302.
