We've got two numbers: 2452 and 7303. Let's find their sum.

Step 1: We'll start by adding the digits 2 & 3 in column 1 and get 5.

Step 2: We'll start by adding the digits 5 & 0 in column 2 and get 5.

Step 3: We'll start by adding the digits 4 & 3 in column 3 and get 7.

Step 4: We'll start by adding the digits 2 & 7 in column 4 and get 9.

So, 2452 + 7303 = 9755.
