Addition and subtraction practice worksheet with no regrouping, ideal for elementary math students.

Let’s solve each problem step by step. Since the worksheet says “No Regrouping,” that means we can add or subtract digit by digit from right to left without borrowing or carrying — but actually, looking at the problems, some *do* require regrouping (like #11: 634 - 235). Wait — let me double-check the title: “Addition & Subtraction with No Regrouping.” That suggests all problems are designed so you don’t need to borrow or carry. But let’s verify each one as we go.

Actually, upon closer inspection of the problems, many of them DO involve digits where subtraction would normally require borrowing — for example, #11: 634 - 235 → in the ones place, 4 - 5 can’t be done without borrowing. So perhaps the title is misleading, or maybe it’s a trick? Or maybe I should just solve them correctly regardless?

Wait — let’s re-read the instruction: “Solve the problem accurately.” So even if the title says “no regrouping,” if the math requires it, we do it properly. But let’s check each problem carefully.

Actually, let me look again — maybe the problems are set up so that no regrouping is needed? Let’s test a few:

#1: 330 + 623 → 0+3=3, 3+2=5, 3+6=9 → 953 ✔ no regrouping

#2: 126 + 243 → 6+3=9, 2+4=6, 1+2=3 → 369 ✔

#3: 373 - 111 → 3-1=2, 7-1=6, 3-1=2 → 262 ✔

#4: 662 - 331 → 2-1=1, 6-3=3, 6-3=3 → 331 ✔

#5: 359 - 210 → 9-0=9, 5-1=4, 3-2=1 → 149 ✔

#6: 412 - 321 → 2-1=1, 1-2 → uh oh! Can’t do 1-2 without borrowing. So this DOES require regrouping. Hmm.

But the title says “No Regrouping.” Maybe it’s a mistake in the worksheet? Or maybe I’m supposed to assume no regrouping and skip those? That doesn’t make sense.

Alternatively, perhaps “No Regrouping” refers to addition only? But there are subtractions too.

Wait — let’s check #6 again: 412 - 321. If we do it without regrouping, we’d get negative digits, which isn’t allowed. So probably, despite the title, we are to solve them correctly, using regrouping when necessary.

But let’s see what the actual correct answers are by solving each properly.

I’ll go through each one carefully.

Problem 1: 330 + 623

Ones: 0 + 3 = 3
Tens: 3 + 2 = 5
Hundreds: 3 + 6 = 9
→ 953

Problem 2: 126 + 243

Ones: 6 + 3 = 9
Tens: 2 + 4 = 6
Hundreds: 1 + 2 = 3
→ 369

Problem 3: 373 - 111

Ones: 3 - 1 = 2
Tens: 7 - 1 = 6
Hundreds: 3 - 1 = 2
→ 262

Problem 4: 662 - 331

Ones: 2 - 1 = 1
Tens: 6 - 3 = 3
Hundreds: 6 - 3 = 3
→ 331

Problem 5: 359 - 210

Ones: 9 - 0 = 9
Tens: 5 - 1 = 4
Hundreds: 3 - 2 = 1
→ 149

Problem 6: 412 - 321

Ones: 2 - 1 = 1
Tens: 1 - 2 → can’t do, so borrow from hundreds.
Hundreds becomes 3, tens become 11.
11 - 2 = 9
Hundreds: 3 - 3 = 0
→ 91

Wait — 412 - 321:
412
-321

Start from right:
2 - 1 = 1
1 - 2 → borrow, so 11 - 2 = 9, and hundreds digit was 4, now 3
3 - 3 = 0
So answer is 91. Correct.

Problem 7: 666 + 333

Ones: 6 + 3 = 9
Tens: 6 + 3 = 9
Hundreds: 6 + 3 = 9
→ 999

Problem 8: 340 - 222

Ones: 0 - 2 → borrow. Tens is 4, becomes 3, ones become 10.
10 - 2 = 8
Tens: 3 - 2 = 1
Hundreds: 3 - 2 = 1
→ 118

Check: 340 - 222 = 118 ✔

Ones: 4 - 5 → borrow. Tens is 3, becomes 2, ones become 14.
