No problem, let's work through this together. We're starting with 2008 and 6470 and adding them all up.

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

Step 2: We'll start by adding the digits 0 & 7 in column 2 and get 7.

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

Step 4: We'll start by adding the digits 2 & 6 in column 4 and get 8.

So, 2008 + 6470 = 8478.
