OK, let's do this. We've got 2341 and 5100 and we're adding them all together.

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

Step 2: We'll start by adding the digits 4 & 0 in column 2 and get 4.

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

Step 4: We'll start by adding the digits 2 & 5 in column 4 and get 7.

So, 2341 + 5100 = 7441.
