No problem, let's work through this together. We're starting with 7045 and 1114 and adding them all up.

Step 1: We'll start by adding the digits 5 & 4 in column 1 and get 9.

Step 2: We'll start by adding the digits 4 & 1 in column 2 and get 5.

Step 3: We'll start by adding the digits 0 & 1 in column 3 and get 1.

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

So, 7045 + 1114 = 8159.
