OK, let's do this. We've got 6045 and 1332 and we're adding them all together.

Step 1: We'll start by adding the digits 5 & 2 in column 1 and get 7.

Step 2: We'll start by adding the digits 4 & 3 in column 2 and get 7.

Step 3: We'll start by adding the digits 0 & 3 in column 3 and get 3.

Step 4: We'll start by adding the digits 6 & 1 in column 4 and get 7.

So, 6045 + 1332 = 7377.
