No problem, let's work through this together. We're starting with 1160 and 3173 and adding them all up.

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 6 & 7 in column 2 and get 13.
We'll write down the last digit 3 and carry the 1 to the next column.

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

Step 4: We'll start by adding the digits 1 & 3 in column 4 and get 4.

So, 1160 + 3173 = 4333.
