Do you have questions about any step or would you like further explanations?

Here are 5 related questions for practice:

1. Can you solve $578 + 192$?
2. What happens when you add $345 + 678$?
3. How do you handle carrying over when adding larger numbers?
4. Solve $999 + 101$.
5. Try adding $256 + 344$.

Tip: Always align numbers by their place values (units, tens, hundreds) to avoid errors when adding.
