Identify the operation: Identify the operation required for solving the problem. In this case, we need to perform addition, which is the operation of finding the total or sum when two or more numbers are put together.
Write down the numbers: Write down the numbers to be added. We have `20` and `30`.
Perform the addition operation: Perform the addition operation. Add the ones place first `(0 + 0),` which equals `0,` and then add the tens place `(2 + 3),` which equals `5`.
Combine the results: Combine the results of the addition to get the final answer. The ones place is `0` and the tens place is `5,` so the sum is `50`.
Verify the result: Verify the result by checking if the addition was done correctly. `20 + 30` is indeed `50,` so the calculation is correct.
