Let's solve this addition problem. We have 2214 and 3215, and we need to add them together.

Step 1: We'll start by adding the digits 4 & 5 in column 1 and get 9.

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

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

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

So, 2214 + 3215 = 5429.
