No problem, let's work through this together. We're starting with 626 and 120 and adding them all up.

Step 1: We'll start by adding the digits 6 & 0 in column 1 and get 6.

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

Step 3: We'll start by adding the digits 6 & 1 in column 3 and get 7.

So, 626 + 120 = 746.
