Let's solve this addition problem. We have 2180 and 7065, and we need to add them together.

Step 1: We'll start by adding the digits 0 & 5 in column 1 and get 5.

Step 2: We'll start by adding the digits 8 & 6 in column 2 and get 14.
We'll write down the last digit 4 and carry the 1 to the next column.

Step 3: We'll start by adding the digits 1 & 0 in column 3 and get 2.

Step 4: We'll start by adding the digits 2 & 7 in column 4 and get 9.

So, 2180 + 7065 = 9245.
