Answer 1

To calculate the sum of 3-digit numbers, add the hundreds place digits, the tens place digits, and the ones place digits together.

Step-by-step explanation:

To calculate the sum of 3-digit numbers, you can use the following strategies:

1. Add the hundreds place digits together.
2. Add the tens place digits together.
3. Add the ones place digits together.

For example, let's calculate the sum of 345 and 567. Adding the hundreds place digits, we get 3 + 5 = 8. Adding the tens place digits, we get 4 + 6 = 10. Adding the ones place digits, we get 5 + 7 = 12. So, the sum of 345 and 567 is 812.
