No problem, let's work through this together. We're starting with 7604 and 1184 and adding them all up.

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

Step 2: We'll start by adding the digits 0 & 8 in column 2 and get 8.

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

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

So, 7604 + 1184 = 8788.
