Let's solve this addition problem. We have 6000 and 2438, and we need to add them together.

Step 1: We'll start by adding the digits 0 & 8 in column 1 and get 8.

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

Step 3: We'll start by adding the digits 0 & 4 in column 3 and get 4.

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

So, 6000 + 2438 = 8438.
