OK, let's do this. We've got 1017 and 8030 and we're adding them all together.

Step 1: We'll start by adding the digits 7 & 0 in column 1 and get 7.

Step 2: We'll start by adding the digits 1 & 3 in column 2 and get 4.

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

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

So, 1017 + 8030 = 9047.
