No problem, let's work through this together. We're starting with 600 and 5078 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 0 & 7 in column 2 and get 7.

Step 3: We'll start by adding the digits 6 & 0 in column 3 and get 6.

Step 4: We'll start by adding the digits 0 & 5 in column 4 and get 5.

So, 600 + 5078 = 5678.
