Let's get this math done. We have 3226 and 4273 and we're going to add them all together.

Step 1: We'll start by adding the digits 6 & 3 in column 1 and get 9.

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

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

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

So, 3226 + 4273 = 7499.
