Sure thing! We've got 510 and 329 and we're gonna add them together.

Step 1: We'll start by adding the digits 0 & 9 in column 1 and get 9.

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

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

So, 510 + 329 = 839.
