Subtraction with zero difficulty interactive worksheet | Live ... - Free Printable

Let’s solve each subtraction problem step by step. We’ll go one at a time, making sure we borrow correctly when needed.

---

1.) 40 - 23

Start from the right:
- 0 - 3 → can’t do, so borrow from tens place.
- 4 becomes 3, and 0 becomes 10.
- 10 - 3 = 7
- 3 - 2 = 1
→ Answer: 17

---

2.) 70 - 18

Right column:
- 0 - 8 → borrow from 7 (becomes 6), 0 becomes 10
- 10 - 8 = 2
Left column:
- 6 - 1 = 5
→ Answer: 52

---

3.) 50 - 25

Right:
- 0 - 5 → borrow, 5 becomes 4, 0 becomes 10
- 10 - 5 = 5
Left:
- 4 - 2 = 2
→ Answer: 25

4.) 800 - 319

We need to borrow across zeros.

Start from right:
- 0 - 9 → borrow from middle zero? But it’s also 0 → go to hundreds.

Breakdown:
- Hundreds: 8 → becomes 7
- Tens: 0 → becomes 10, but we need to lend to ones → so tens become 9, ones become 10
Now:
- Ones: 10 - 9 = 1
- Tens: 9 - 1 = 8
- Hundreds: 7 - 3 = 4
→ Answer: 481

Wait — let me double-check:

800
-319
= ?

Do 800 - 300 = 500
Then 500 - 19 = 481 → yes.

→ Answer: 481

5.) 600 - 327

Same idea.

Borrowing:

Hundreds: 6 → 5
Tens: 0 → 10 → then lend to ones → becomes 9
Ones: 0 → 10

Now:
- Ones: 10 - 7 = 3
- Tens: 9 - 2 = 7
- Hundreds: 5 - 3 = 2
→ Answer: 273

Check: 600 - 300 = 300; 300 - 27 = 273 → correct.

---

6.) 900 - 136

Borrow:

Hundreds: 9 → 8
Tens: 0 → 10 → lend to ones → becomes 9
Ones: 0 → 10

Ones: 10 - 6 = 4
Tens: 9 - 3 = 6
Hundreds: 8 - 1 = 7
→ Answer: 764

Check: 900 - 100 = 800; 800 - 36 = 764 → good.

---

7.) 400 - 122

Borrow:

Hundreds: 4 → 3
Tens: 0 → 10 → lend to ones → becomes 9
Ones: 0 → 10

Ones: 10 - 2 = 8
Tens: 9 - 2 = 7
Hundreds: 3 - 1 = 2
→ Answer: 278

Check: 400 - 100 = 300; 300 - 22 = 278 → correct.

---

8.) 700 - 443

Borrow:

Hundreds: 7 → 6
Tens: 0 → 10 → lend to ones → becomes 9
Ones: 0 → 10

Ones: 10 - 3 = 7
Tens: 9 - 4 = 5
Hundreds: 6 - 4 = 2
→ Answer: 257

Check: 700 - 400 = 300; 300 - 43 = 257 → yes.

---

9.) 8,000 - 2,112

This is bigger, but same idea.

Write as:

8000
- 2112
______

Start from right:

Ones: 0 - 2 → borrow
But all are zeros until thousands.

So:

Thousands: 8 → 7
Hundreds: 0 → 10 → but needs to lend to tens → becomes 9
Tens: 0 → 10 → lend to ones → becomes 9
Ones: 0 → 10

Now subtract:

Ones: 10 - 2 = 8
Tens: 9 - 1 = 8
Hundreds: 9 - 1 = 8
Thousands: 7 - 2 = 5
→ Answer: 5,888

Check: 8000 - 2000 = 6000; 6000 - 112 = 5888 → correct.

---

10.) 9,008 - 4,671

Align:

9008
- 4671
______

Ones: 8 - 1 = 7
Tens: 0 - 7 → can’t → borrow from hundreds
But hundreds is 0 → borrow from thousands.

Thousands: 9 → 8
Hundreds: 0 → 10 → now lend to tens → hundreds become 9, tens become 10

Now tens: 10 - 7 = 3
Hundreds: 9 - 6 = 3
Thousands: 8 - 4 = 4
Ones already done: 7

→ Answer: 4,337

Check: 9008 - 4000 = 5008; 5008 - 671 = ?

5008 - 600 = 4408; 4408 - 71 = 4337 → yes.

---

11.) 7,000 - 3,333

Borrowing chain:

Thousands: 7 → 6
Hundreds: 0 → 10 → lend to tens → 9
Tens: 0 → 10 → lend to ones → 9
Ones: 0 → 10

Subtract:

Ones: 10 - 3 = 7
Tens: 9 - 3 = 6
Hundreds: 9 - 3 = 6
Thousands: 6 - 3 = 3
→ Answer: 3,667

Check: 7000 - 3000 = 4000; 4000 - 333 = 3667 → correct.

---

12.) 5,004 - 1,983

Align:

5004
- 1983
______

Ones: 4 - 3 = 1
Tens: 0 - 8 → can’t → borrow from hundreds
Hundreds is 0 → borrow from thousands.

Thousands: 5 → 4
Hundreds: 0 → 10 → lend to tens → becomes 9
Tens: 0 → 10 → now subtract 8 → 2
Hundreds: 9 - 9 = 0
Thousands: 4 - 1 = 3

Wait — let's write it clearly:

After borrowing:

Thousands: 4
Hundreds: 9 (after lending to tens)
Tens: 10 (but we borrowed for ones? No — ones was fine)

Actually:

Original: 5004

We only need to borrow for tens place.

So:

Ones: 4 - 3 = 1 ✔

Tens: 0 - 8 → need to borrow from hundreds → but hundreds is 0 → so borrow from thousands.

Thousands: 5 → 4
Hundreds: 0 → 10 → now lend to tens → hundreds become 9, tens become 10

Now:

Tens: 10 - 8 = 2
Hundreds: 9 - 9 = 0
Thousands: 4 - 1 = 3

So result: 3,021

Wait — let me check with another way:

5004 - 1983

Do 5004 - 2000 = 3004
But we subtracted 17 too many (because 2000 - 1983 = 17)
So add back 17: 3004 + 17 = 3021 → yes!

→ Answer: 3,021
