Let's get this math done. We have 1181 and 7206 and we're going to add them all together.

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

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

Step 3: We'll start by adding the digits 1 & 2 in column 3 and get 3.

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

So, 1181 + 7206 = 8387.
