🔍 Explanation:

These are all basic two-digit addition problems. For each, we simply add the two numbers together:

- Start by adding the ones place (right digits), then the tens place (left digits).
- If the sum of the ones is more than 9, carry over to the tens place.

For example:
35 + 25:
- 5 + 5 = 10 → write down 0, carry 1
- 3 + 2 + 1 (carry) = 6 → so 60

But most of these don’t require carrying, so they’re straightforward.
