Ready to do some math? We're starting with 2080 and 5420 and adding them up.

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

Step 2: We'll start by adding the digits 8 & 2 in column 2 and get 10.
We'll write down the last digit 0 and carry the 1 to the next column.

Step 3: We'll start by adding the digits 0 & 4 in column 3 and get 5.

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

So, 2080 + 5420 = 7500.
