OK, let's do this. We've got 2214 and 7366 and we're adding them all together.

Step 1: We'll start by adding the digits 4 & 6 in column 1 and get 10.
We'll write down the last digit 0 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 1 & 6 in column 2 and get 8.

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

Step 4: We'll start by adding the digits 2 & 7 in column 4 and get 9.

So, 2214 + 7366 = 9580.
