Let's solve this addition problem. We have 3221 and 2046, and we need to add them together.

Step 1: We'll start by adding the digits 1 & 6 in column 1 and get 7.

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

Step 3: We'll start by adding the digits 2 & 0 in column 3 and get 2.

Step 4: We'll start by adding the digits 3 & 2 in column 4 and get 5.

So, 3221 + 2046 = 5267.
