No problem, let's work through this together. We're starting with 7467 and are subtracting 845 from it.

Step 1: We'll start by subtracting the digit 5 and the borrow 0 from 7 in column 1 and get 2.
2 is the first digit of our result.

Step 2: We'll start by subtracting the digit 4 and the borrow 0 from 6 in column 2 and get 2.
2 is the next digit of our result.

Step 3: We'll start by subtracting the digit 8 and the borrow 0 from 4 in column 3 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

Step 4: We'll start by subtracting the digit 0 and the borrow 1 from 7 in column 4 and get 6.
6 is the next digit of our result.

So, 7467 - 845 = 6622.
