Not to worry, we've got 2300 and 243. Let's get to adding them!

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

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

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

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

So, 2300 + 243 = 2543.
