No problem, let's work through this together. We're starting with 1068 and 7223 and adding them all up.

Step 1: We'll start by adding the digits 8 & 3 in column 1 and get 11.
We'll write down the last digit 1 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 6 & 2 in column 2 and get 9.

Step 3: We'll start by adding the digits 0 & 2 in column 3 and get 2.

Step 4: We'll start by adding the digits 1 & 7 in column 4 and get 8.

So, 1068 + 7223 = 8291.
