Subtraction worksheets with three-digit numbers arranged in a grid format for place value practice.

Let’s solve each subtraction problem one by one. We’ll go column by column — starting from the right (Ones), then Tens, then Hundreds. If we can’t subtract a bigger number from a smaller one in a column, we’ll borrow from the next column to the left.

Problem 1:
```
925
- 389
------
```

Start with Ones:
5 - 9 → Can’t do! Borrow 1 from Tens.
Tens digit is 2 → becomes 1, and Ones become 15.
15 - 9 = 6

Now Tens:
We had 2, borrowed 1 → now it’s 1.
1 - 8 → Can’t do! Borrow 1 from Hundreds.
Hundreds digit is 9 → becomes 8, and Tens become 11.
11 - 8 = 3

Now Hundreds:
We had 9, borrowed 1 → now it’s 8.
8 - 3 = 5

Answer: 536

Problem 2:
```
842
- 478
------
```

Ones:
2 - 8 → Can’t do! Borrow from Tens.
Tens is 4 → becomes 3, Ones become 12.
12 - 8 = 4

Tens:
Had 4, borrowed 1 → now 3.
3 - 7 → Can’t do! Borrow from Hundreds.
Hundreds is 8 → becomes 7, Tens become 13.
13 - 7 = 6

Hundreds:
Had 8, borrowed 1 → now 7.
7 - 4 = 3

Answer: 364

Problem 3:
```
523
- 297
------
```

Ones:
3 - 7 → Can’t do! Borrow from Tens.
Tens is 2 → becomes 1, Ones become 13.
13 - 7 = 6

Tens:
Had 2, borrowed 1 → now 1.
1 - 9 → Can’t do! Borrow from Hundreds.
Hundreds is 5 → becomes 4, Tens become 11.
11 - 9 = 2

Hundreds:
Had 5, borrowed 1 → now 4.
4 - 2 = 2

Answer: 226

Problem 4:
```
6_4
- _79
------
```

Wait — this looks like there are missing digits. Let’s look again.

Actually, looking at the layout:

It says:
```
6 _ 4
- _ 7 9
-------
```

But that doesn’t make sense unless we assume blanks mean zero? Or maybe it’s a typo?

Wait — let me re-express based on alignment.

Looking at the original image description, Problem 4 is written as:

```
6 4
- 7 9
---------
```

That would be:

```
064
- 079
-----
```

But 64 - 79 is negative — which isn’t typical for elementary worksheets.

Alternatively, perhaps it's meant to be:

```
604
- 79
-----
```

Because sometimes spaces are used instead of zeros.

Let’s assume that — because otherwise it doesn’t work.

So:

```
604
- 79
-----
```

Align properly:

```
604
- 079
-----
```

Ones:
4 - 9 → Can’t do! Borrow from Tens.
Tens is 0 → can’t lend! So borrow from Hundreds.

Hundreds: 6 → becomes 5
Tens: 0 → becomes 10, but needs to lend to Ones → so Tens become 9, Ones become 14.

Ones: 14 - 9 = 5

Tens: 9 - 7 = 2

Hundreds: 5 - 0 = 5

Answer: 525

*(Note: This assumes the blank was meant to be 0 — common in such worksheets when space is left.)*

Problem 5:
```
832
- 556
------
```

Ones:
2 - 6 → Can’t do! Borrow from Tens.
Tens is 3 → becomes 2, Ones become 12.
12 - 6 = 6

Tens:
Had 3, borrowed 1 → now 2.
2 - 5 → Can’t do! Borrow from Hundreds.
Hundreds is 8 → becomes 7, Tens become 12.
12 - 5 = 7

Hundreds:
Had 8, borrowed 1 → now 7.
7 - 5 = 2

Answer: 276

Problem 6:
```
726
- 447
------
```

Ones:
6 - 7 → Can’t do! Borrow from Tens.
Tens is 2 → becomes 1, Ones become 16.
16 - 7 = 9

Tens:
Had 2, borrowed 1 → now 1.
1 - 4 → Can’t do! Borrow from Hundreds.
Hundreds is 7 → becomes 6, Tens become 11.
11 - 4 = 7

Hundreds:
Had 7, borrowed 1 → now 6.
6 - 4 = 2

Answer: 279
