Subtraction worksheet with regrouping exercises and interactive questions.

Let’s solve each subtraction problem step by step. We’ll check if we need to regroup (borrow) and then find the answer.

---

Problem 1: 36 - 29

- Is the number in the ones place of the top number (6) smaller than the bottom number (9)?
→ Yes, 6 < 9 → So we need to regroup.

- Regroup: Take 1 from the tens place (3 becomes 2), add 10 to the ones place (6 becomes 16).

Now subtract:
- Ones: 16 - 9 = 7
- Tens: 2 - 2 = 0

Answer: 7

Check: Did I borrow? Yes → Circle “Yes” under “Did I regroup?”
Is there a zero on top after borrowing? No — the tens digit became 2, not 0 → Circle “No” under “Is there a zero on top?”
Do I have to borrow from the next column? No — we only had two digits → Circle “No”

Final Answer for #1: 7

Problem 2: 68 - 43

- Ones place: 8 vs 3 → 8 > 3 → No regrouping needed.

Subtract:
- Ones: 8 - 3 = 5
- Tens: 6 - 4 = 2

Answer: 25

Check: Did I regroup? No → Circle “No”
Zero on top? No → Circle “No”
Borrow from next column? No → Circle “No”

Final Answer for #2: 25

Problem 3: 416 - 39

This is a 3-digit minus 2-digit. Line them up:

```
416
- 39
-----
```

Start from right (ones place):

- Ones: 6 vs 9 → 6 < 9 → Need to regroup.

Look at tens place: it’s 1. Can’t borrow from 1? Actually, we can — but let’s do it carefully.

Step 1: Borrow from tens place for ones place.

But tens digit is 1 → so we need to go to hundreds place first.

Actually, better way:

We have 416.

Ones: 6 - 9 → can’t do → borrow from tens.

Tens digit is 1 → so we borrow from hundreds.

Hundreds: 4 becomes 3
Tens: 1 becomes 11 (because we borrowed 1 hundred = 10 tens, added to existing 1 ten → 11 tens)

Now, borrow 1 ten for the ones place:

Tens: 11 becomes 10
Ones: 6 becomes 16

Now subtract:

Ones: 16 - 9 = 7
Tens: 10 - 3 = 7
Hundreds: 3 - 0 = 3 (since 39 has no hundreds)

Answer: 377

Wait — that doesn’t match what’s written below the problem (“17”). That must be a mistake in the worksheet or my reading.

Wait — looking again: The problem says:

```
416
- 39
-----
17 ← this is probably just an example or placeholder? Or maybe misaligned?
```

Actually, no — 416 - 39 is NOT 17. Let me recalculate.

416 - 39:

Break it down: 416 - 30 = 386; 386 - 9 = 377.

So correct answer is 377, not 17. But the worksheet shows “17” under the line — that might be a typo or part of the student’s work.

But since we’re solving correctly, we ignore that.

Back to questions:

Did I regroup? YES — multiple times → Circle “Yes”

Is there a zero on top? After borrowing, tens digit became 10, then we borrowed again → became 9? Wait, let’s track:

Original: 4 (hundreds), 1 (tens), 6 (ones)

After borrowing for ones:

- Hundreds: 4 → 3
- Tens: 1 → 11 (after getting 10 from hundreds)
- Then borrow 1 ten for ones: tens become 10, ones become 16

Then subtract:

Ones: 16 - 9 = 7
Tens: 10 - 3 = 7
Hundreds: 3 - 0 = 3

So final number: 377

In the process, did any digit become zero on top? The tens digit was 10 before subtracting — but we didn’t leave it as zero; we subtracted 3 from it. So no zero left on top → Circle “No” for “Is there a zero on top?”

Do I have to borrow from the next column? We did borrow from hundreds to tens, then tens to ones — so yes, we borrowed across columns → Circle “Yes” for “Do I have to borrow from the next column?”

But wait — the question says: “Do I have to borrow from the next column?” — meaning during the process, did we need to go left to borrow? Yes → so “Yes”

Final Answer for #3: 377

But hold on — maybe the problem is actually 416 - 399? No, it says 39.

Alternatively, perhaps the “17” shown is the result of 416 - 399? No, that would be negative.

I think the “17” is just a distractor or error. We proceed with correct math.

Actually — wait! Looking back at the image description — the user wrote:

“Name: ___________ Learning to Subtract with Regrouping - Worksheet #1”

And under problem 3, it shows:

```
416
- 39
-----
17
```

That 17 is likely the student’s incorrect answer. We are to solve correctly.

So our answer is 377.

But let’s double-check with another method:

416 - 39 = ?

Add 1 to both to make it easier: 417 - 40 = 377 → same answer.

Yes.

So for problem 3: Answer is 377

Questions:

- Did I regroup? → Yes
- Is there a zero on top? → No (we had 10 in tens, but subtracted 3, got 7 — no zero remains)
- Do I have to borrow from the next column? → Yes (we borrowed from hundreds to tens, then tens to ones)

Problem 4: 76 - 44

Ones: 6 - 4 = 2
Tens: 7 - 4 = 3
Answer: 32

Regroup? 6 > 4 → No
Zero on top? No
Borrow from next? No

Final Answer: 32

Problem 5: 42 - 16

Ones: 2 < 6 → need to regroup.

Borrow from tens: 4 becomes 3, 2 becomes 12

Ones: 12 - 6 = 6
Tens: 3 - 1 = 2
Answer: 26

Regroup? Yes
Zero on top? No (tens became 3, not 0)
Borrow from next? No (only two digits)

Final Answer: 26

Problem 6: 83 - 23

Ones: 3 - 3 = 0
Tens: 8 - 2 = 6
Answer: 60

Regroup? 3 = 3 → no need → No
Zero on top? No
Borrow from next? No

Final Answer: 60

Now, compiling all answers:

1. 36 - 29 = 7
2. 68 - 43 = 25
3. 416 - 39 = 377
4. 76 - 44 = 32
5. 42 - 16 = 26
6. 83 - 23 = 60

For the checkboxes:

Problem 1:
- Did I regroup? → Yes
- Is there a zero on top? → No
- Do I have to borrow from the next column? → No

Problem 2:
All No

Problem 3:
- Did I regroup? → Yes
- Is there a zero on top? → No
- Do I have to borrow from the next column? → Yes

Problem 4:
All No

Problem 5:
- Did I regroup? → Yes
- Is there a zero on top? → No
- Do I have to borrow from the next column? → No

Problem 6:
All No

Note: For problem 3, “Do I have to borrow from the next column?” — since we borrowed from hundreds to tens, and then tens to ones, yes, we did borrow from the next column (leftward). So “Yes”.

Also, for “Is there a zero on top?” — in problem 3, after borrowing, the tens digit was 10, then we subtracted 3 to get 7 — so no zero remains on top. So “No”.

Similarly, in other problems, no zeros remain on top after subtraction.
