No problem, let's work through this together. We're starting with 5542 and 3005 and adding them all up.

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

Step 2: We'll start by adding the digits 4 & 0 in column 2 and get 4.

Step 3: We'll start by adding the digits 5 & 0 in column 3 and get 5.

Step 4: We'll start by adding the digits 5 & 3 in column 4 and get 8.

So, 5542 + 3005 = 8547.
