No problem, let's work through this together. We're starting with 3012 and 5047 and adding them all up.

Step 1: We'll start by adding the digits 2 & 7 in column 1 and get 9.

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

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

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

So, 3012 + 5047 = 8059.
