OK, let's do this. We've got 1655 and 4232 and we're adding them all together.

Step 1: We'll start by adding the digits 5 & 2 in column 1 and get 7.

Step 2: We'll start by adding the digits 5 & 3 in column 2 and get 8.

Step 3: We'll start by adding the digits 6 & 2 in column 3 and get 8.

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

So, 1655 + 4232 = 5887.
