Let's solve each of the addition problems on the worksheet. The task is to
add 3-digit and 2-digit numbers without regrouping, which means we will add the digits in each place (ones, tens, hundreds) separately, ensuring that no digit sum exceeds 9 in any column.
We'll go through each problem step by step:
---
1. 280 + 18
- Ones: 0 + 8 = 8
- Tens: 8 + 1 = 9
- Hundreds: 2 + 0 = 2
✔ 298
---
2. 613 + 84
- Ones: 3 + 4 = 7
- Tens: 1 + 8 = 9
- Hundreds: 6 + 0 = 6
✔ 697
