Let's get this math done. We have 1039 and 8255 and we're going to add them all together.

Step 1: We'll start by adding the digits 9 & 5 in column 1 and get 14.
We'll write down the last digit 4 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 3 & 5 in column 2 and get 9.

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

Step 4: We'll start by adding the digits 1 & 8 in column 4 and get 9.

So, 1039 + 8255 = 9294.
