No problem, let's work through this together. We're starting with 112 and 710 and adding them all up.

Step 1: We'll start by adding the digits 2 & 0 in column 1 and get 2.

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

Step 3: We'll start by adding the digits 1 & 7 in column 3 and get 8.

So, 112 + 710 = 822.
