No problem, let's work through this together. We're starting with 4711 and 152 and adding them all up.

Step 1: We'll start by adding the digits 1 & 2 in column 1 and get 3.

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 7 & 1 in column 3 and get 8.

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

So, 4711 + 152 = 4863.
