Alright, let's solve this problem step by step. We have 327 and 425 and we're adding them together.

Step 1: We'll start by adding the digits 7 & 5 in column 1 and get 12.
We'll write down the last digit 2 and carry the 1 to the next column.

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

Step 3: We'll start by adding the digits 3 & 4 in column 3 and get 7.

So, 327 + 425 = 752.
