No problem, let's work through this together. We're starting with 6700 and 3012 and adding them all up.

Step 1: We'll start by adding the digits 0 & 2 in column 1 and get 2.

Step 2: We'll start by adding the digits 0 & 1 in column 2 and get 1.

Step 3: We'll start by adding the digits 7 & 0 in column 3 and get 7.

Step 4: We'll start by adding the digits 6 & 3 in column 4 and get 9.

So, 6700 + 3012 = 9712.
