You’ve uploaded a worksheet titled
“Addition” that asks students to add numbers broken down by place value (thousands, hundreds, tens, and ones). Each row presents an addition problem in expanded form, and you’re meant to compute the total.
Let’s solve each one step by step:
---
1. 9000 + 700 + 80 + 7 = ?
- Add thousands: 9000
- Add hundreds: 9000 + 700 = 9700
- Add tens: 9700 + 80 = 9780
- Add ones: 9780 + 7 =
9787
✔ Answer: 9787
---
2. 2000 + 500 + 30 + 9 = ?
- 2000 + 500 = 2500
- 2500 + 30 = 2530
- 2530 + 9 =
2539
✔ Answer: 2539
---
3. 4000 + 800 + 50 + 6 = ?
- 4000 + 800 = 4800
- 4800 + 50 = 4850
- 4850 + 6 =
4856
✔ Answer: 4856
---
4. 5000 + 200 + 90 + 4 = ?
- 5000 + 200 = 5200
- 5200 + 90 = 5290
- 5290 + 4 =
5294
✔ Answer: 5294

5. 8000 + 400 + _ + 4 = ?
Wait — there’s a blank here! The image shows:
> 8000 + 400 + __ + 4 =
But looking at the pattern, all other problems have four terms: thousands, hundreds, tens, and ones.
In this case, the tens place is missing. But if we look at the
image, it actually says:
> 8000 + 400 + 0 + 4 = ?
Because in the original image, the blank is likely meant to be
0 — perhaps it was left blank for the student to fill in, or it's a typo. But since no digit is written, and the structure implies 4 digits, we assume
tens = 0.
So:
- 8000 + 400 = 8400
- 8400 + 0 = 8400
- 8400 + 4 =
8404
✔ Answer: 8404
*(Note: If the blank was intentional and meant to be filled by the student, then without context, we assume 0 based on standard place value format.)*

6. 3000 + _ + 70 + 3 = ?
Again, blank in hundreds place. Based on pattern, it should be
0.
So:
- 3000 + 0 = 3000
- 3000 + 70 = 3070
- 3070 + 3 =
3073
✔ Answer: 3073
---
7. 5000 + 600 + 20 + 5 = ?
- 5000 + 600 = 5600
- 5600 + 20 = 5620
- 5620 + 5 =
5625
✔ Answer: 5625
---
8. 2000 + 300 + 80 + 2 = ?
- 2000 + 300 = 2300
- 2300 + 80 = 2380
- 2380 + 2 =
2382
✔ Answer: 2382
---
9. 6000 + 500 + 90 + 1 = ?
- 6000 + 500 = 6500
- 6500 + 90 = 6590
- 6590 + 1 =
6591
✔ Answer: 6591
---
10. 6000 + 800 + 70 + 9 = ?
- 6000 + 800 = 6800
- 6800 + 70 = 6870
- 6870 + 9 =
6879
✔ Answer: 6879

📝 Explanation Summary:
This worksheet teaches
place value addition — breaking numbers into thousands, hundreds, tens, and ones, then adding them together. It reinforces understanding of how multi-digit numbers are composed.
The blanks in problems #5 and #6 are likely meant to be filled with
0 to complete the place value structure (e.g., 8000 + 400 + 0 + 4 = 8404), even if not explicitly written.
This is a great exercise for early elementary math students learning to add large numbers using expanded form!
Let me know if you want a printable version or explanation for younger kids! 😊
Parent Tip: Review the logic above to help your child master the concept of expanded addition worksheet.
