OK, let's do this. We've got 5030 and 1156 and we're adding them all together.

Step 1: We'll start by adding the digits 0 & 6 in column 1 and get 6.

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

Step 3: We'll start by adding the digits 0 & 1 in column 3 and get 1.

Step 4: We'll start by adding the digits 5 & 1 in column 4 and get 6.

So, 5030 + 1156 = 6186.
