Let's get this math done. We have 7026 and 1438 and we're going to add them all together.

Step 1: We'll start by adding the digits 6 & 8 in column 1 and get 14.
We'll write down the last digit 4 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 2 & 3 in column 2 and get 6.

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 7 & 1 in column 4 and get 8.

So, 7026 + 1438 = 8464.
