No problem, let's work through this together. We're starting with 3080 and 1211 and adding them all up.

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

Step 2: We'll start by adding the digits 8 & 1 in column 2 and get 9.

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

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

So, 3080 + 1211 = 4291.
