OK, let's do this. We've got 2074 and 3114 and we're adding them all together.

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 7 & 1 in column 2 and get 8.

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 2 & 3 in column 4 and get 5.

So, 2074 + 3114 = 5188.
