No problem, let's work through this together. We're starting with 5263 and 1031 and adding them all up.

Step 1: We'll start by adding the digits 3 & 1 in column 1 and get 4.

Step 2: We'll start by adding the digits 6 & 3 in column 2 and get 9.

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 5 & 1 in column 4 and get 6.

So, 5263 + 1031 = 6294.
