No problem, let's work through this together. We're starting with 205 and 9180 and adding them all up.

Step 1: We'll start by adding the digits 5 & 0 in column 1 and get 5.

Step 2: We'll start by adding the digits 0 & 8 in column 2 and get 8.

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

Step 4: We'll start by adding the digits 0 & 9 in column 4 and get 9.

So, 205 + 9180 = 9385.
