OK, let's do this. We've got 1461 and 4038 and we're adding them all together.

Step 1: We'll start by adding the digits 1 & 8 in column 1 and get 9.

Step 2: We'll start by adding the digits 6 & 3 in column 2 and get 9.

Step 3: We'll start by adding the digits 4 & 0 in column 3 and get 4.

Step 4: We'll start by adding the digits 1 & 4 in column 4 and get 5.

So, 1461 + 4038 = 5499.
