Let’s solve each addition problem step by step. Remember, we’re adding numbers with regrouping — that means if a column adds up to 10 or more, we carry the extra digit to the next column on the left.
We’ll go row by row, left to right.

First Row:
1.
246 + 483
- Ones: 6 + 3 = 9 → write 9
- Tens: 4 + 8 = 12 → write 2, carry 1
- Hundreds: 2 + 4 + 1 (carry) = 7 → write 7
→
Answer: 729
2.
509 + 287
- Ones: 9 + 7 = 16 → write 6, carry 1
- Tens: 0 + 8 + 1 = 9 → write 9
- Hundreds: 5 + 2 = 7 → write 7
→
Answer: 796
3.
452 + 356
- Ones: 2 + 6 = 8 → write 8
- Tens: 5 + 5 = 10 → write 0, carry 1
