1. **Stating the problem:** Solve the first addition problem: (i) 47 + 2. 2. **Formula and rules:** Addition is combining two numbers to get their total sum. We add digits starting from the rightmost place value (units), carrying over if the sum exceeds 9. 3. **Intermediate work:** $$47 + 2 = 49$$ 4. **Explanation:** Adding 2 to 7 in the units place gives 9, and the tens place digit 4 remains unchanged. 5. **Final answer:** The sum is $49$. This completes the solution for the first problem.
