Let's get this math done. We have 2258 and 6029 and we're going to add them all together.

Step 1: We'll start by adding the digits 8 & 9 in column 1 and get 17.
We'll write down the last digit 7 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 5 & 2 in column 2 and get 8.

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

Step 4: We'll start by adding the digits 2 & 6 in column 4 and get 8.

So, 2258 + 6029 = 8287.
