Sure thing! We've got 215 and 200 and we're gonna add them together.

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 1 & 0 in column 2 and get 1.

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

So, 215 + 200 = 415.
