No problem, let's work through this together. We're starting with 51 and 6118 and adding them all up.

Step 1: We'll start by adding the digits 1 & 8 in column 1 and get 9.

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

Step 3: We'll start by adding the digits 0 & 1 in column 3 and get 1.

Step 4: We'll start by adding the digits 0 & 6 in column 4 and get 6.

So, 51 + 6118 = 6169.
