Addition Regrouping Worksheet 4th Grade - Free Printable

Let’s solve each addition problem step by step. We’ll add the numbers column by column, starting from the right (ones place), then tens, then hundreds — just like you do on paper.

---

1) 527 + 94 - 138

First, add 527 + 94:

- Ones: 7 + 4 = 11 → write down 1, carry over 1
- Tens: 2 + 9 = 11, plus carried 1 = 12 → write down 2, carry over 1
- Hundreds: 5 + 0 = 5, plus carried 1 = 6

So, 527 + 94 = 621

Now subtract 138:

- Ones: 1 - 8 → can’t do, borrow from tens → 11 - 8 = 3
- Tens: 1 (after borrowing) - 3 → can’t do, borrow from hundreds → 11 - 3 = 8
- Hundreds: 5 (after borrowing) - 1 = 4

Answer: 483

Wait — let me double-check that subtraction:

621
-138
= ?

Ones: 1 < 8 → borrow → 11 - 8 = 3
Tens: 1 (was 2, borrowed 1) → now 1, but need to subtract 3 → borrow again → 11 - 3 = 8
Hundreds: 5 (was 6, borrowed 1) → 5 - 1 = 4
→ 483 ✔

2) 264 + 605 - 38

Add 264 + 605:

- Ones: 4 + 5 = 9
- Tens: 6 + 0 = 6
- Hundreds: 2 + 6 = 8

→ 869

Subtract 38:

- Ones: 9 - 8 = 1
- Tens: 6 - 3 = 3
- Hundreds: 8 - 0 = 8

→ 831

Check: 869 - 38 = 831 ✔

---

3) 471 + 328 - 133

Add 471 + 328:

- Ones: 1 + 8 = 9
- Tens: 7 + 2 = 9
- Hundreds: 4 + 3 = 7

→ 799

Subtract 133:

- Ones: 9 - 3 = 6
- Tens: 9 - 3 = 6
- Hundreds: 7 - 1 = 6

→ 666

✔

---

4) 845 - 169 - 246

First, 845 - 169:

- Ones: 5 - 9 → borrow → 15 - 9 = 6
- Tens: 3 (after borrow) - 6 → borrow → 13 - 6 = 7
- Hundreds: 7 (after borrow) - 1 = 6

→ 676

Now 676 - 246:

- Ones: 6 - 6 = 0
- Tens: 7 - 4 = 3
- Hundreds: 6 - 2 = 4

→ 430

✔

5) 714 + 67 - 528

Add 714 + 67:

- Ones: 4 + 7 = 11 → write 1, carry 1
- Tens: 1 + 6 = 7, plus 1 = 8
- Hundreds: 7

→ 781

Subtract 528:

- Ones: 1 - 8 → borrow → 11 - 8 = 3
- Tens: 7 (after borrow) - 2 = 5
- Hundreds: 7 - 5 = 2

→ 253

✔

---

6) 801 + 158 + 26

Add all three:

Start with 801 + 158:

- Ones: 1 + 8 = 9
- Tens: 0 + 5 = 5
- Hundreds: 8 + 1 = 9 → 959

Now +26:

- Ones: 9 + 6 = 15 → write 5, carry 1
- Tens: 5 + 2 = 7, plus 1 = 8
- Hundreds: 9

→ 985

✔

---

7) 682 + 251 + 735

Add step by step:

682 + 251:

- Ones: 2 + 1 = 3
- Tens: 8 + 5 = 13 → write 3, carry 1
- Hundreds: 6 + 2 = 8, plus 1 = 9 → 933

Now +735:

- Ones: 3 + 5 = 8
- Tens: 3 + 3 = 6
- Hundreds: 9 + 7 = 16 → write 6, carry 1 → thousands: 1

→ 1668

✔

8) 89 - 362 - 814

This is tricky — we’re subtracting bigger numbers from a small one.

Do left to right:

89 - 362 = negative number

362 - 89 = 273 → so 89 - 362 = -273

Then -273 - 814 = -(273 + 814) = -1087

But wait — maybe the problem meant to add? Let me check original image...

Looking back at user input: “COLUMN ADDITION 3 DIGITS MULTI-ADDITIONS SHEET 1”

Ah! The title says “MULTI-ADDITIONS” — probably means adding multiple numbers, even if some have minus signs? But in standard math, minus means subtract.

But looking at layout — it's written as:

8) 89
-362
-814

That would be 89 - 362 - 814 = -1087

But perhaps it’s a typo and should be +? Or maybe it’s testing negatives?

Since this is for school students, likely they expect positive answers — let me recheck the image description.

User wrote: “COLUMN ADDITION 3 DIGITS MULTI-ADDITIONS SHEET 1”

And in the list, #8 is:

8) 89
-362
-814

Hmm. Maybe it’s meant to be added as absolute values? Unlikely.

Alternatively, perhaps the minus signs are part of the number? Like -362 and -814 being added to 89?

In that case: 89 + (-362) + (-814) = same as above: -1087

But since other problems give positive results, maybe I misread.

Wait — looking at original text:

“8) 89
-362
-814”

It’s possible the dash is not minus, but a separator? No, in context, others use + and -.

Actually, in the first row, #1 has “+94 -138”, so dashes mean subtract.

So for #8, it’s 89 minus 362 minus 814.

Which is indeed -1087.

But let’s confirm calculation:

89 - 362 = -273
-273 - 814 = -1087 ✔

Okay, we’ll go with that.

9) 435 + 176 - 82

Add 435 + 176:

- Ones: 5 + 6 = 11 → write 1, carry 1
- Tens: 3 + 7 = 10, plus 1 = 11 → write 1, carry 1
- Hundreds: 4 + 1 = 5, plus 1 = 6 → 611

Subtract 82:

- Ones: 1 - 2 → borrow → 11 - 2 = 9
- Tens: 0 (after borrow) - 8 → borrow → 10 - 8 = 2
- Hundreds: 5 (after borrow) - 0 = 5

→ 529

✔

10) 681 + 45 - 309

Add 681 + 45:

- Ones: 1 + 5 = 6
- Tens: 8 + 4 = 12 → write 2, carry 1
- Hundreds: 6 + 0 = 6, plus 1 = 7 → 726

Subtract 309:

- Ones: 6 - 9 → borrow → 16 - 9 = 7
- Tens: 1 (after borrow) - 0 = 1
- Hundreds: 7 - 3 = 4

→ 417

11) 901 + 154 - 66

Add 901 + 154:

- Ones: 1 + 4 = 5
- Tens: 0 + 5 = 5
- Hundreds: 9 + 1 = 10 → write 0, carry 1 → 1055

Subtract 66:

- Ones: 5 - 6 → borrow → 15 - 6 = 9
- Tens: 4 (after borrow) - 6 → borrow → 14 - 6 = 8
- Hundreds: 9 (after borrow) - 0 = 9

→ 989

✔

12) 372 + 185 - 636

Add 372 + 185:

- Ones: 2 + 5 = 7
- Tens: 7 + 8 = 15 → write 5, carry 1
- Hundreds: 3 + 1 = 4, plus 1 = 5 → 557

Subtract 636:

557 - 636 → negative

636 - 557 = 79 → so answer is -79

13) 716 + 459 - 243

Add 716 + 459:

- Ones: 6 + 9 = 15 → write 5, carry 1
- Tens: 1 + 5 = 6, plus 1 = 7
- Hundreds: 7 + 4 = 11 → write 1, carry 1 → 1175

Subtract 243:

- Ones: 5 - 3 = 2
- Tens: 7 - 4 = 3
- Hundreds: 1 - 2 → borrow → 11 - 2 = 9, thousands: 0

→ 932

Wait: 1175 - 243:

Ones: 5-3=2
Tens: 7-4=3
Hundreds: 1-2 → can't, borrow from thousands → 11-2=9, thousands becomes 0
→ 932 ✔

14) 584 + 384 + 508

Add step by step:

584 + 384:

- Ones: 4+4=8
- Tens: 8+8=16 → write 6, carry 1
- Hundreds: 5+3=8, plus 1=9 → 968

Now +508:

- Ones: 8+8=16 → write 6, carry 1
- Tens: 6+0=6, plus 1=7
- Hundreds: 9+5=14 → write 4, carry 1 → 1476

→ 1476

✔

- Ones: 8+3=11 → write 1, carry 1
- Tens: 7+0=7, plus 1=8
- Hundreds: 3+4=7 → 781

Now +280:

- Ones: 1+0=1
- Tens: 8+8=16 → write 6, carry 1
- Hundreds: 7+2=9, plus 1=10 → write 0, carry 1 → 1061

→ 1061

✔

16) 611 - 784 - 59 - 552

Left to right:

611 - 784 = -173

-173 - 59 = -232

-232 - 552 = -784

Check:

784 + 59 = 843; 843 + 552 = 1395; 1395 - 611 = 784 → so yes, -784
