Let's get this math done. We have 2287 and 3100 and we're going to add them all together.

Step 1: We'll start by adding the digits 7 & 0 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 2 & 1 in column 3 and get 3.

Step 4: We'll start by adding the digits 2 & 3 in column 4 and get 5.

So, 2287 + 3100 = 5387.
