No problem, let's work through this together. We're starting with 6040 and 3318 and adding them all up.

Step 1: We'll start by adding the digits 0 & 8 in column 1 and get 8.

Step 2: We'll start by adding the digits 4 & 1 in column 2 and get 5.

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 & 3 in column 4 and get 9.

So, 6040 + 3318 = 9358.
