Let's get this math done. We have 9309 and 450 and we're going to add them all together.

Step 1: We'll start by adding the digits 9 & 0 in column 1 and get 9.

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

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

Step 4: We'll start by adding the digits 9 & 0 in column 4 and get 9.

So, 9309 + 450 = 9759.
