No problem, let's work through this together. We're starting with 302 and 1010 and adding them all up.

Step 1: We'll start by adding the digits 2 & 0 in column 1 and get 2.

Step 2: We'll start by adding the digits 0 & 1 in column 2 and get 1.

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

Step 4: We'll start by adding the digits 0 & 1 in column 4 and get 1.

So, 302 + 1010 = 1312.
