Okay, let's tackle this math problem. We're starting with 92925 and subtracting 49982.

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

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

Step 3: We'll start by subtracting the digit 9 and the borrow 1 from 9 in column 3 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

Step 4: We'll start by subtracting the digit 9 and the borrow 1 from 2 in column 4 and get -8.
We add -8 to 10 and get 2 as the next digit of the result.

Step 5: We'll start by subtracting the digit 4 and the borrow 1 from 9 in column 5 and get 4.
4 is the next digit of our result.

So, 92925 - 49982 = 42943.
