No problem, let's work through this together. We're starting with 6010 and 1459 and adding them all up.

Step 1: We'll start by adding the digits 0 & 9 in column 1 and get 9.

Step 2: We'll start by adding the digits 1 & 5 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 6 & 1 in column 4 and get 7.

So, 6010 + 1459 = 7469.
