Mixed Triple Addition and Subtraction Without Regrouping - Free Printable

Let’s solve each problem step by step. We’re doing triple-digit addition and subtraction without regrouping, which means we can add or subtract each column (ones, tens, hundreds) directly without borrowing or carrying.

We’ll go row by row, left to right.

---

First Row:

1. 460 - 320
→ 400 - 300 = 100
→ 60 - 20 = 40
→ 0 - 0 = 0
→ Total: 140

2. 593 + 904
→ 500 + 900 = 1400
→ 90 + 0 = 90
→ 3 + 4 = 7
→ Total: 1497

3. 217 + 221
→ 200 + 200 = 400
→ 10 + 20 = 30
→ 7 + 1 = 8
→ Total: 438

4. 717 - 614
→ 700 - 600 = 100
→ 10 - 10 = 0
→ 7 - 4 = 3
→ Total: 103

---

Second Row:

5. 310 + 242
→ 300 + 200 = 500
→ 10 + 40 = 50
→ 0 + 2 = 2
→ Total: 552

6. 386 - 112
→ 300 - 100 = 200
→ 80 - 10 = 70
→ 6 - 2 = 4
→ Total: 274

7. 350 - 200
→ 300 - 200 = 100
→ 50 - 0 = 50
→ 0 - 0 = 0
→ Total: 150

8. 233 + 542
→ 200 + 500 = 700
→ 30 + 40 = 70
→ 3 + 2 = 5
→ Total: 775

---

Third Row:

9. 366 - 161
→ 300 - 100 = 200
→ 60 - 60 = 0
→ 6 - 1 = 5
→ Total: 205

10. 241 + 342
→ 200 + 300 = 500
→ 40 + 40 = 80
→ 1 + 2 = 3
→ Total: 583

11. 214 - 102
→ 200 - 100 = 100
→ 10 - 0 = 10
→ 4 - 2 = 2
→ Total: 112

12. 311 + 484
→ 300 + 400 = 700
→ 10 + 80 = 90
→ 1 + 4 = 5
→ Total: 795

---

Fourth Row:

13. 104 - 4
→ This is just 104 minus 4 in the ones place.
→ 100 + (4 - 4) = 100 + 0 = 100

14. 700 + 89
→ 700 + 0 = 700 (hundreds)
→ 0 + 80 = 80 (tens)
→ 0 + 9 = 9 (ones)
→ Total: 789

15. 477 - 373
→ 400 - 300 = 100
→ 70 - 70 = 0
→ 7 - 3 = 4
→ Total: 104

16. 214 - 102
→ Wait — this is the same as #11! Let’s double-check:
→ 200 - 100 = 100
→ 10 - 0 = 10
→ 4 - 2 = 2
→ Total: 112 ✔

Wait — looking back at the image layout, the fourth row has:

Left side:
104 - 4
700 + 89
477 - 373
214 - 102 ← but that’s already done above? Actually, let me check the original grid again.

Actually, looking at the structure:

The worksheet has 4 rows × 4 columns = 16 problems.

Row 4:

- 104 - 4 → 100
- 700 + 89 → 789
- 477 - 373 → 104
- 214 - 102 → 112 ← yes, it appears twice? Or maybe I misread.

Wait — actually, in the fourth row, last one is “214 - 102” — same as third row, third column? No — let's list all 16 clearly:

From top-left to bottom-right:

Row 1:
460 - 320 = 140
593 + 904 = 1497
217 + 221 = 438
717 - 614 = 103

Row 2:
310 + 242 = 552
386 - 112 = 274
350 - 200 = 150
233 + 542 = 775

Row 3:
366 - 161 = 205
241 + 342 = 583
214 - 102 = 112
311 + 484 = 795

Row 4:
104 - 4 = 100
700 + 89 = 789
477 - 373 = 104
214 - 102 = 112 ← wait, this is repeated? But in the image, the last one in row 4 is “214 - 102”? Actually, looking again — no, in the fourth row, the last one is “214 - 102” — but that was already in row 3, column 3. That might be a typo in the worksheet? Or perhaps I’m misreading.

Wait — let me recheck the original image description from user:

In the fourth row, the problems are:

Left sheet:
104 - 4
700 + 89
477 - 373
214 - 102 ← but that’s the same as earlier? Hmm.

Actually, looking carefully — in the fourth row, the last problem on the left sheet is “214 - 102”, but on the right sheet, the fourth row ends with “214 - 102” too? That seems odd.

Wait — perhaps I made a mistake. Let me recount the positions.

Actually, the worksheet has two identical grids? No — the user uploaded an image with two pages side by side? But the instruction says “solve the problem” — probably meaning all 16 problems shown.

But in the fourth row, the last problem is listed as “214 - 102” — which we already calculated as 112. So even if it repeats, the answer is still 112.

Alternatively, maybe it’s “214 - 102” for both? That’s fine — we’ll compute it again.

But let’s verify 477 - 373:

477
-373
= (400-300)=100, (70-70)=0, (7-3)=4 → 104 ✔️

And 214 - 102:

214
-102
= 100 + 10 + 2 = 112 ✔️

So all answers are consistent.

Now, let’s compile the final answers in order, row by row, left to right.

Final Answers:

Row 1: 140, 1497, 438, 103
Row 2: 552, 274, 150, 775
Row 3: 205, 583, 112, 795
Row 4: 100, 789, 104, 112

I’ve double-checked each calculation. All are correct under “no regrouping” rules — meaning no borrowing or carrying needed, which holds true for all these problems.
