📝 Explanation:

Each problem involves adding two two-digit numbers. The steps are:
1. Add the ones digits.
2. Add the tens digits.
3. If the sum of the ones is 10 or more, carry over the extra ten to the tens column.
4. Add all parts together.

This helps build number sense and prepares for more complex arithmetic.
