Let's solve this addition problem. We have 2012 and 1474, and we need to add them together.

Step 1: We'll start by adding the digits 2 & 4 in column 1 and get 6.

Step 2: We'll start by adding the digits 1 & 7 in column 2 and get 8.

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 & 1 in column 4 and get 3.

So, 2012 + 1474 = 3486.
