No problem, let's work through this together. We're starting with 2094 and 7064 and adding them all up.

Step 1: We'll start by adding the digits 4 & 4 in column 1 and get 8.

Step 2: We'll start by adding the digits 9 & 6 in column 2 and get 15.
We'll write down the last digit 5 and carry the 1 to the next column.

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

Step 4: We'll start by adding the digits 2 & 7 in column 4 and get 9.

So, 2094 + 7064 = 9158.
