No problem, let's work through this together. We're starting with 218 and 360 and adding them all up.

Step 1: We'll start by adding the digits 8 & 0 in column 1 and get 8.

Step 2: We'll start by adding the digits 1 & 6 in column 2 and get 7.

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

So, 218 + 360 = 578.
