Math 2 worksheet from Inocencio Integrated School featuring twelve subtraction problems ranging from two-digit to four-digit numbers.

Let’s solve each subtraction problem step by step. We’ll work from right to left (ones, tens, hundreds, etc.), borrowing when needed.

---

1.) 40 - 23

- Ones: 0 - 3 → can’t do, borrow from tens.
- Tens become 3, ones become 10 → 10 - 3 = 7
- Tens: 3 - 2 = 1
→ 17

2.) 70 - 18

- Ones: 0 - 8 → borrow from tens
- Tens become 6, ones become 10 → 10 - 8 = 2
- Tens: 6 - 1 = 5
→ 52

3.) 50 - 25

- Ones: 0 - 5 → borrow from tens
- Tens become 4, ones become 10 → 10 - 5 = 5
- Tens: 4 - 2 = 2
→ 25

4.) 800 - 319

- Ones: 0 - 9 → borrow from tens → but tens is 0, so borrow from hundreds
- Hundreds: 8 → 7, tens: 0 → 9 (after borrowing), ones: 0 → 10
- Now: 10 - 9 = 1
- Tens: 9 - 1 = 8
- Hundreds: 7 - 3 = 4
→ 481

5.) 600 - 327

- Ones: 0 - 7 → borrow from tens → tens is 0 → borrow from hundreds
- Hundreds: 6 → 5, tens: 0 → 9, ones: 0 → 10
- 10 - 7 = 3
- Tens: 9 - 2 = 7
- Hundreds: 5 - 3 = 2
→ 273

6.) 900 - 136

- Ones: 0 - 6 → borrow from tens → tens is 0 → borrow from hundreds
- Hundreds: 9 → 8, tens: 0 → 9, ones: 0 → 10
- 10 - 6 = 4
- Tens: 9 - 3 = 6
- Hundreds: 8 - 1 = 7
→ 764

7.) 400 - 122

- Ones: 0 - 2 → borrow from tens → tens is 0 → borrow from hundreds
- Hundreds: 4 → 3, tens: 0 → 9, ones: 0 → 10
- 10 - 2 = 8
- Tens: 9 - 2 = 7
- Hundreds: 3 - 1 = 2
→ 278

8.) 700 - 443

- Ones: 0 - 3 → borrow from tens → tens is 0 → borrow from hundreds
- Hundreds: 7 → 6, tens: 0 → 9, ones: 0 → 10
- 10 - 3 = 7
- Tens: 9 - 4 = 5
- Hundreds: 6 - 4 = 2
→ 257

9.) 8,000 - 2,112

- Ones: 0 - 2 → borrow from tens → tens is 0 → borrow from hundreds → hundreds is 0 → borrow from thousands
- Thousands: 8 → 7, hundreds: 0 → 9, tens: 0 → 9, ones: 0 → 10
- 10 - 2 = 8
- Tens: 9 - 1 = 8
- Hundreds: 9 - 1 = 8
- Thousands: 7 - 2 = 5
→ 5,888

10.) 9,008 - 4,671

- Ones: 8 - 1 = 7
- Tens: 0 - 7 → borrow from hundreds → hundreds is 0 → borrow from thousands
- Thousands: 9 → 8, hundreds: 0 → 9, tens: 0 → 10
- But we need to borrow for tens: tens becomes 10, then lend 1 to ones? Wait — ones already done.

Actually:

Start over:

Thousands: 9, Hundreds: 0, Tens: 0, Ones: 8

Subtract 4,671:

Ones: 8 - 1 = 7 ✔

Tens: 0 - 7 → can’t → borrow from hundreds → but hundreds is 0 → borrow from thousands

Thousands: 9 → 8

Hundreds: 0 → 9 (but now we need to borrow for tens)

Tens: 0 → 10 → then lend 1 to tens? Wait — let’s break it:

After borrowing:

Thousands: 8

Hundreds: 9 (from 0 after borrowing from thousands)

But tens is still 0 → so borrow from hundreds:

Hundreds: 9 → 8

Tens: 0 → 10

Now subtract:

Tens: 10 - 7 = 3

Hundreds: 8 - 6 = 2

Thousands: 8 - 4 = 4

Ones: 7

→ 4,337

Wait — let me double-check:

9,008
-4,671
= ?

Do it vertically:

9008
- 4671
------
Start from right:

8 - 1 = 7
0 - 7 → borrow → look at next digit (0) → also 0 → go to 9

So:

Thousands: 9 → 8
Hundreds: 0 → 9 (after borrowing) → then lend to tens → becomes 8
Tens: 0 → 10 → then lend to ones? No, ones already done.

Actually:

We have:

9 0 0 8
- 4 6 7 1
----------

Ones: 8 - 1 = 7

Tens: 0 - 7 → need to borrow. The hundreds place is 0, so we go to thousands.

Thousands: 9 → 8

Hundreds: 0 → 9 (but we need to borrow for tens, so hundreds becomes 8, tens becomes 10)

Tens: 10 - 7 = 3

Hundreds: 8 - 6 = 2

Thousands: 8 - 4 = 4

So: 4,337

✔ Correct.

11.) 7,000 - 3,333

- Ones: 0 - 3 → borrow from tens → tens is 0 → borrow from hundreds → hundreds is 0 → borrow from thousands
- Thousands: 7 → 6, hundreds: 0 → 9, tens: 0 → 9, ones: 0 → 10
- 10 - 3 = 7
- Tens: 9 - 3 = 6
- Hundreds: 9 - 3 = 6
- Thousands: 6 - 3 = 3
→ 3,667

12.) 5,004 - 1,983

- Ones: 4 - 3 = 1
- Tens: 0 - 8 → borrow from hundreds → hundreds is 0 → borrow from thousands
- Thousands: 5 → 4, hundreds: 0 → 9, tens: 0 → 10
- But we need to borrow for tens: tens becomes 10, then lend 1 to tens? Wait:

Actually:

Thousands: 5 → 4

Hundreds: 0 → 9 (after borrowing) → then lend to tens → becomes 8

Tens: 0 → 10 → then subtract 8 → 10 - 8 = 2

Hundreds: 8 - 9 → can’t! Oh no — mistake.

Let’s redo carefully:

5004
- 1983
------

Ones: 4 - 3 = 1 ✔

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

Thousands: 5 → 4

Hundreds: 0 → 9 (but we need to borrow for tens, so hundreds becomes 8, tens becomes 10)

Tens: 10 - 8 = 2 ✔

Hundreds: 8 - 9 → can’t! Problem.

Ah — here’s the error: when we borrow from thousands to hundreds, hundreds becomes 10? No.

Standard way:

To subtract 1983 from 5004:

Write as:

5 0 0 4
- 1 9 8 3
----------

Start from right:

Ones: 4 - 3 = 1

Tens: 0 - 8 → can’t → borrow from hundreds → but hundreds is 0 → so borrow from thousands.

Thousands: 5 → 4

Now hundreds: 0 → 10 (because we borrowed 1 thousand = 10 hundreds)

But we need to borrow for tens, so hundreds lend 1 to tens → hundreds become 9, tens become 10

Now:

Tens: 10 - 8 = 2

Hundreds: 9 - 9 = 0

Thousands: 4 - 1 = 3

So: 3,021

Check: 5004 - 1983 = ?

5004 - 2000 = 3004, but we subtracted 17 too much (since 2000 - 1983 = 17), so add back 17 → 3004 + 17 = 3021 ✔

→ 3,021
