Let's get this math done. We have 610 and 243 and we're going to add them all together.

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

Step 2: We'll start by adding the digits 1 & 4 in column 2 and get 5.

Step 3: We'll start by adding the digits 6 & 2 in column 3 and get 8.

So, 610 + 243 = 853.
